Machine Head is an American HeavyMetal band formed in Oakland, California in 1992 by vocalist/guitarist Robert Flynn, who had departed from the ThrashMetal band Music/{{Violence}} due to ''actual violence'' between Flynn and the rest of the band, and gang members. Flynn cofounded Machine Head, named for the Music/DeepPurple album, ''[[Music/MachineHeadAlbum Machine Head]]'' with bassist Adam Duce, and the new band started off playing a fusion of GrooveMetal and ThrashMetal.

With the release of the band's third album, 1999's ''The Burning Red'', NuMetal elements were also added, including semi-rapped vocals and guitar licks that imitated turntable scratching. The band's fans accused Machine Head of "selling out"; but Machine Head countered that they weren't trying to sound like other bands, just that they wanted to sound different.

After guitarist Ahrue Luster (responsible for the band's NuMetal influence) left the band due to creative differences, Machine Head initially decided to begin writing as a three-piece band, but temporary guitarist Phil Demmel (formerly of Vio-lence) became a permanent member of the band. The band's style has since evolved into a fusion of melodic elements with groove and thrash now dominating the band's style again.

On 22 February 2013, long-time bassist Adam Duce was fired from the band. His departure makes Rob Flynn the sole remaining original member of the band. He was replaced by former Sanctity frontman Jared [=MacEachern=].

Machine Head's eighth studio album,''Bloodstone & Diamonds'', was released on November 7th 2014 to critical acclaim and debuted at #21 on the Billboard charts, the band's highest chart position to date. It was also their first album not to be on Roadrunner Records, instead being on Nuclear Blast which they are currently signed to as of now.

The band's ninth studio album, ''Catharsis'', will be released on January 26th, 2018.

!!Machine Head provides examples of the following tropes:


[[folder:The band members themselves/live performance]]
* BaldOfAwesome: The band's drummer Dave [=McClain=].
* IllBoy: Phil Demmel suffers from Cardiogenic Syncope which caused him to faint or lose consciousness couple times in concert.
* InsultBackfire: About a month before the release of Catharsis, the band's Facebook page put up a picture of a scathing review of it and took a moment to insult the reviewer. The comment section didn't agree with the band.
* PuttingTheBandBackTogether: Sort of, Phil Demmel was Robb's bandmate in Vio-Lence.
* TookALevelInBadass: In order to top ''The Blackening'', the entire band took additional lessons in their instrument of choice prior to recording ''[[EvenBetterSequel Unto the Locust]]'' , and holy hell [[EpicRiff does]] [[EpicRocking it]] [[CrowningMusicOfAwesome show]].
* OlderThanHeLooks: Robb has always looked younger than he was. [[http://upload.wikimedia.org/wikipedia/en/a/a4/From_This_Day_Cover.JPG On this single cover]], he's the blonde guy with the goatee. He was 31. [[http://wac.450f.edgecastcdn.net/80450F/loudwire.com/files/2011/10/robb-flynn.jpg This is him last year at 43.]], looking to be around his late 20s. He aged quite a bit in the last year-and-a-half, but still doesn't look 44, but [[http://images.epiphone.com.s3.amazonaws.com/News/2012/rob%20flynn%20in%20germany.jpginstead around his 30s.]]
* TeenGenius: Flynn was apparently known for his skill as a guitarist while he was still in high school; Craig Locicero of Forbidden (which Flynn was a member of when they were still known as Forbidden Evil) recounted how Flynn was able to play the entirety of Electric Sun's "Earthquake" when he was just a teenager.

* TakeThat: "Aesthetics of Hate" from ''The Blackening'' is one directed at an article of the same name that [[SpeakIllOfTheDead praised the murder of]] [[Music/{{Pantera}} Dimebag Darrell]].
--> "For the love of brother, I will sing this [[PrecisionFStrike fucking]] song! Aesthetics of Hate, I hope you [[PunctuatedForEmphasis Burn! In! Heeeeeellll!!]]
* TheFamilyThatSlaysTogether: "The Night Of Long Knives" from ''Bloodstone & Diamonds'' is about [[UsefulNotes/CharlesManson the Manson family.]]
* WeUsedToBeFriends: "Game Over" from ''Bloodstone & Diamonds'' is about a friendship destroyed and the singer retrospectively renouncing the cynicism he'd been subjected to over the years.
** Rumor is that the target is former bassist Adam Duce, who Robb fired and was later sued by.


[[folder:Music/Music referential]]
* CoverVersion: Of [[Music/ThePolice "Message in a Bottle"]], [[Music/BlackSabbath "Hole in the Sky"]], [[Music/{{Metallica}} "Creeping Death", "Battery"]], [[Music/IronMaiden "Hallowed Be Thy Name"]], [[Music/{{Pantera}} "Fucking Hostile"]], [[Music/JudasPriest "The Sentinel"]], and [[Music/{{Rush}} "Witch Hunt"]]. Amazingly enough, they've also covered [[Music/{{Nirvana}} Negative Creep]].
* EpicRocking: They had their moments early on, but since ''The Blackening'' it became their primary modus operandi.
* MetalScream: Type 1
* MohsScaleOfRockAndMetalHardness: Generally about an 8. With songs like Violate and Down to None falling into the 7 category and Descend the Shades Of Night being a little hard to pin down on this scale (the softer sections are about a 2, but the harder sections are 7-8). A couple songs, such as "Blood for Blood" and the first half of "Struck a Nerve," go up to a 9.
** Sail Into the Black from ''Bloodstone & Diamonds'' is the most variant Machine Head song yet, with the first half being a solid 2 with smoke-laden lyrics, piano and foreboding guitar. The second half kicks in and sends things all the way to 7 with the third (and fourth) verse, then simmering down to 5 with the chorus, instrumental and finale.
* NewSoundAlbum: ''Burn My Eyes'' and ''The More Things Change'' were essentially straightforward GrooveMetal, with some songs having more of a ThrashMetal influence, though ''The More Things Change'' was where they started to include NuMetal elements. ''The Burning Red'' and ''Supercharger'' added more elements of NuMetal, including rapped vocals on some songs. ''Through the Ashes of Empires'' was a return to GrooveMetal with a side of melodic metalcore, a sound which the band has mostly stuck with since, but focusing more heavily on ThrashMetal with some more progressive elements on ''The Blackening'' and ''Unto the Locust''. ''Catharsis'' was a return to their nu era stylistically.
* OminousLatinChanting: The first part of "I Am Hell".
* ReasonYouSuckSpeech: The song "Left Unfinished" is essentially one big "Fuck you" to Rob Flynn's abusive birth parents (he was rescued from them and placed into a foster home when he was five years old).
* UpToEleven: From ''Unto the Locust'' could be this to ''The Blackening''.

[[folder:Music Videos]]
* ChestBurster: Phil in the video for "The Locust". One shot shows a swarm of locusts flying out of a wound in his chest.
* TheSwarm: "The Locust" features, well, [[ExactlyWhatItSaysOnTheTin a swarm of locusts]].
