Rivers of Nihil is an American progressive death metal band. Known for their eclectic sound that folds in the assorted influences of all of its members, they have become a fast-rising star in the death metal world and are poised to take it by storm.

Formed in Reading, Pennsylvania in 2009 by Jake Dieffenbach (vocals), Jonathan Kunz (guitar), and Ron Nelson (drums), the band quickly welcomed in Brody Uttley (guitar) and Adam Biggs (bass, vocals) after their own band fell apart and then proceeded to build up a live reputation that helped make ''Hierarchy'', their debut EP, an underground hit in 2010. Shows throughout the Northeast helped continue the momentum, as did their second EP, ''Temporality Unbound'', which came out in late 2011. It was sometime around this period that [[Music/HateEternal Erik Rutan]] discovered them on [=MySpace=] and left them a message praising them and informing them of his desire to work with them someday. This, along with a successful tour with their buddies in Kamikabe, only served to further embolden them; when offered a deal with Metal Blade Records in 2012, it became apparent that their hard work had paid off. Recording for their full-length began in March of 2013; come that October, ''The Conscious Seed of Light'' was released and met with much fanfare and critical acclaim. Various tours followed; additionally, 2014 brought the band's first hiccup, as Ron Nelson decided to leave and was replaced by Alan Balamut. Additionally, their first major tour of that year with Oceano, Broken Hope, Fallujah, and Kublai Khan ended early due to a string of ill fortune that struck every band on the bill except them and resulted in the cancellation of the tour; thankfully, another tour with Whitechapel and [=DevilDriver=] was just around the corner and went fine, so it's likely that that was just a bump in the road. Kunz later quit in September and was replaced by Jon Topore, and the band is currently preparing to embark on the "Swamp Leper Stomp" tour with the newest [[Music/{{Death}} Death to All]] lineup, Obituary, and Massacre. Their second album, ''Monarchy'', is slated for a late summer 2015 release. Around the end of 2015, Alan Balamut left due to a mix of a rough financial situation and a desire to finally finish school; Dylan Potts was brought on as a live fill-in and was inducted as a full-time member sometime after. He did not work out and was gone by the end of 2016, however, and Jared Klein was brought in as a fill-in before being made full-time himself in 2017.

!!The band contains examples of the following tropes:
* AlbumTitleDrop:
** "Central Antheneum":
-->"I return my psyche to the origin of self!
--> Through this plane of space and time!
--> '''The conscious seed of light!'''"
* TheAllegedCar: Even by metal standards, their old van was a piece of shit and they were more than happy to admit it. Adam even walked one interviewer through all the bizarre and frustrating quirks of it, which included lots of bad sensors that essentially made most of the indicator lights and dials on the dashboard worthless, bad locks that rendered several doors largely unusable, and frustrating air conditioning quirks that seemed to be indicative of larger electrical problems; Digital Tour Bus (who were given an overview of the old van) even told them that it was quite literally the worst tour vehicle that they had ever covered. They got a newer, much better one, however, and their old one presumably met its end in a scrapyard.
* ApocalypseHow: "Mechanical Trees" features a Class 1 that is fast on its way to Class 2; civilization still exists, but the atmosphere is so thoroughly polluted that breathable air has to be created by the titular devices. Eventually turns into a Class 3 by the end of ''Monarchy''.
* AscendedExtra: Dylan Potts and Jared Klein were both originally live fill-ins before being asked to join full-time, though the former was kicked out after roughly a year. Adam Biggs was apparently also this, as he was not a founding member and had previously tracked bass on their first demo as a session member before joining full-time.
* AudienceParticipationSong: "Sand Baptism".
* BadassBeard: Jake and Brody.
* CantHoldHisLiquor: Jake, apparently.
* ConceptAlbum: All of their albums in varying degrees:
** Zigzagged with ''The Conscious Seed of Light'': it's not a full concept album, but it is thematically based around spring and has several songs ("Mechanical Trees" and "Airless") that set up ''Monarchy''.
** ''Monarchy'': the world of "Mechanical Trees" and "Airless" has become a sun-bleached desert and civilization is mostly restricted to a sun-worshiping theocracy that has started to look more and more like a dictatorship with each passing day. [[spoiler:Then a mass die-off occurs]].
** ''Where Owls Know My Name'': the world of ''Monarchy'' is dead and gone and the spirit of the planet has allowed one person to live so that its death may have a witness, which doubles as a general narrative of death, aging, loss, and the ephemerality of life.
* EarlyInstallmentWeirdness: ''Hierarchy'' was ''way'' more straightforward and less adventurous than the releases that followed and was generally pretty clear-cut Morbid Angel worship.
* EpicRocking: "Subtle Change" (8:34), "Capricorn/Agoratopia" (7:50), "Suntold" (7:23), "Where Owls Know My Name" (6:42), "The Silent Life" (6:34), "Circles in the Sky" (6:27), and "Death Is Real" (6:09).
* GeniusLoci: The planet of ''Monarchy''. By ''Where Owls Know My Name'', it's on its deathbed and has chosen the protagonist to accompany it on its last days.
* GrowingTheBeard: Adam Biggs credits [[Music/HateEternal Erik Rutan]] for making him a better bassist overall. In the band's earlier days, he just wanted to play the most complex and challenging material that he could come up with on bass and went into the recording sessions for ''The Conscious Seed of Light'' with that approach in mind; according to Biggs, Rutan kept pushing him to calm down, let the song breathe, and let the music dictate his approach rather than trying to shoehorn what he felt like playing in. Biggs has long since realized that Rutan's influence rubbed off on him and made him a more mature, nuanced player.
* HandicappedBadass: Jake Dieffenbach has a progressively-worsening hearing deficit that he was born with that requires him to wear hearing aids (it's also resulted in a noticeable lisp due to how his hearing difficulties affected the way that he learned how to speak as a child), but he has become known as a powerful vocalist with a distinctly intelligible vocal approach.
* IAmSong: "Sand Baptism".
-->"I AM THE SUN!
-->I AM THE MOON!"
* IndecipherableLyrics: Averted with Jake, who has a very clear and intelligible vocal style.
* LeadBassist: Adam Biggs hits all four categories on the head; he's got a ton of technical ability, he's a relatively frequent vocal contributor, he writes the vast majority of the lyrics and a decent amount of the music as well, and his basslines factor very heavily into the band's established musical style.
* LyricalColdOpen: "ALTERNATING PERSONALITY!"
* MetalScream: Type 1 for Jake, Type 3 for Adam.
* MohsScaleOfRockAndMetalHardness: Moderate 10.
* MushroomSamba: "Place of Serpents" (ayahuasca).
* NewAgeRetroHippie: Jake is something of this; while not overly hippie-ish in appearance, he is heavily into a lot of New Age philosophies, the likes of which tend to shape their lyrics.
* NewSoundAlbum: Both releases since ''The Conscious Seed of Light'' have involved major stylistic shifts.
** ''Monarchy'' is a far denser, less straightforward, and generally more progressive release than the debut; while the first half is at least somewhat similar, the second half is where the arrangements open up.
** ''Where Owls Know My Name'' is a much deeper plunge into prog, with far more eclectic arrangements and the introduction of clean vocals, saxophone, and Mellotron on certain tracks.
* OdeToIntoxication: "Place of Serpents", in this case ayahuasca.
* PerishingAltRockVoice: Biggs' cleans circa ''Where Owls Know My Name''.
* PintsizedPowerhouse: Jake Dieffenbach.
* ProgressiveMetal: Particularly circa ''Where Owls Know My Name''.
* ReligionOfEvil: "A Fertile Altar", which is about a sex cult; while no names are mentioned, it has been confirmed that it was inspired by multiple high-profile incidents.
* RockTrio: ''Extremely'' early in their career. They apparently played a few shows as this before they added in Uttley and Biggs after their own band folded, though Biggs had previously recorded bass on their first demo as a session member.
* SignatureStyle: Lots of odd-timed riffs, atmospheric tremolo riffing, quiet, post-rock-influenced sections, the occasional full-speed blasting portion, and darkly melodic soloing.
* SingingVoiceDissonance: Jake's surprisingly clear and intelligible mid-ranged roar stands in stark contrast to his ''heavily'' lisped speaking voice.
* SopranoAndGravel: Sorta. Jake has a mid-ranged roar that is somewhere between [[Music/MorbidAngel Steve Tucker]] and [[Music/{{Vader}} Piotr Wiwczarek]], while Adam has a much higher rasp. Played straight on ''Where Owls Know My Name'', which features clean vocals on multiple tracks.
* SpecialGuest: Zach Strouse tracked saxophone on multiple songs on ''Where Owls Know My Name'', while [[Music/BlackCrownInitiate Andy Thomas]] tracked guest cleans on the aforementioned album's title track and [[Music/TheFaceless Justin McKinney]] laid down a lead on "Old Nothing". On the live front, Dylan Potts and Jared Klein both started out as this, while Darren Liwen (The Kennedy Veil, Dismal) was strictly a one-time fill-in.
* StartMyOwn: Jon Kunz started the death/doom metal act Outer Heaven sometime in 2013 and later wound up quitting Rivers of Nihil to focus on it.
* TechnicalDeathMetal: Their [=EPs=] and the first two studio albums. They abandoned this on ''Where Owls Know My Name''.
* TrueCompanions: With Music/{{Revocation}}.
