CountryMusic band consisting of Zac Brown (guitar, lead vocals), Jimmy De Martini (fiddle, backing vocals), John Driskell Hopkins (bass, banjo, ukulele, guitar, backing vocals), Coy Bowles (keyboards), Chris Fryar (drums), Clay Cook (guitar, organ, piano, pedal steel, mandolin, backing vocals), Matt Mangano (bass guitar), and Daniel de los Reyes (percussion). The band enjoyed several years of independent success in its native Atlanta, Georgia under a slightly different and smaller lineup of just Brown, Hopkins (who was then the bassist), De Martini, and little-known Marcus Petruska and Tim Ussery, the latter of whom was briefly replaced by Joel Williams.

After a series of independent albums, the band broke through in 2008 with the song "Chicken Fried". Originally released through a now-defunct indie label, the song was picked up by Creator/AtlanticRecords partway through its chart run and included on the album ''The Foundation''. By this point, Cook had joined. "Chicken Fried" made them only the second country band ever to send its debut single to #1 on the ''Billboard'' country charts, and three of the other album's four singles topped the charts as well. Oh, and they won the 2010 Grammy Award for Best New Artist. Following two live albums, 2010's ''You Get What You Give'' notched four more chart-toppers, including a duet with Music/AlanJackson on "As She's Walking Away".

de Los Reyes joined just before their third album, ''Uncaged'', which included the smashes "Goodbye in Her Eyes" and "Sweet Annie", along with the Music/JasonMraz-penned "Jump Right In". This was also their last album under the production of Keith Stegall, best known for his work with Jackson. Matt Mangano joined in 2013, taking over as bassist so that Hopkins could begin playing other instruments as well, just in time for an EP produced by Music/DaveGrohl.

''Jekyll + Hyde'' followed in 2015, producing the country hits "Homegrown", "Loving You Easy", and "Beautiful Drug". This album included a vast array of collaborators such as Music/ChrisCornell, Music/SaraBareilles, and Music/CeeLoGreen, and a cover of alt-country singer Jason Isbell's "Dress Blues". The Cornell collaboration, "Heavy Is the Head", introduced the band's hard-rock influences for the first time, and even topped the Mainstream Rock charts (making them only the second act after Music/BonJovi to have both a #1 country and #1 mainstream rock hit). Alt-country producer Dave Cobb took the boards for the band's fifth major-label album ''Welcome Home'', led off by the tender ballad "My Old Man".

The band is known for its wide array of instrumentation and musical styles to the point of GenreRoulette, all usually anchored by Brown's nylon-string guitar, De Martini's fiddle, and the band's strong four-part harmonies.

!!Tropes present:
* AlbumTitleDrop: ''You Get What You Give'' is title-dropped in "Martin".
* AnimatedMusicVideo: "The Wind" has one animated by Creator/MikeJudge. Yes, ''that'' Mike Judge.
* BadassBeard: Zac Brown.
* {{Bowdlerize}}: Several radio edits of "Toes" exist, primarily censoring "ass in the sand" in the chorus and "roll a big fat one". The official edit changes "ass in the sand" to "toes in the sand" and silences "fat one", although some stations made their own edits and others just play the uncensored album version. Zac was not pleased, but his co-writer didn't mind.
* BrokenRecord: "No, we don't have a lot of money" is sung seven times in a row on "Free".
* ContinuityNod: Floaty Boatwood, the fictional lead in the "Toes" video, reappears in "Knee Deep" and "Jump Right In".
* DooWopProgression: "As She's Walking Away" uses this in the first half of its verses.
* EarlyInstallmentWeirdness: Their first album as a whole is a lot more mainstream ("Chicken Fried" in particular stands out as being far more StrictlyFormula than anything else they've put out to date), lacking the GenreRoulette and overall instrumental interplay of its successors. It also has little-known original members Marcus Petruska and Joel Williams.
* EpicInstrumentalOpener: The album version of "Free" opens with a minute-long fiddle solo.
* GenreRoulette: Southern rock, jam band, bluegrass, mainstream country? It's all there. ''Jekyll + Hyde'' pushes it UpToEleven with hard rock ("Heavy Is the Head", "Junkyard"), jazz ("Mango Tree", with Music/SaraBareilles), EDM ("Beautiful Drug"), and more.
* LongRunnerLineup: In an unusual variant of this trope, the band's most famous lineup has grown by three members without anyone leaving.
* LoveIsADrug: "Beautiful Drug" uses the well known metaphor ("Such a beautiful drug, I can't get enough / Got a habit and I'm dying for a hit of your love...").
* MotorMouth: "The Wind" is ''really'' freaking fast.
* NiceHat: Zac's skullcap.
* OnceAnEpisode: Every album except the ''Grohl Sessions'' EP has an upbeat beach-themed song that gets released in the summer ("Toes", "Knee Deep", "Jump Right In", "Castaway").
* OneWomanSong: "Sweet Annie".
* RearrangeTheSong:
** For some reason, the radio edit of "Chicken Fried" abridges some of the solos and has a few barely discernible organ notes dubbed into the last chorus.
** The radio edit of "All Alright" removes A. J. Ghent's guitar solo before the bridge.
** There's a remix of "Beautiful Drug" that lessens the EDM elements in favor of more fiddle.
** "Castaway" was remixed for radio by moving the fadeout to the beginning and toning down the bridge a bit.
* SignatureStyle: Heavy focus on instrumentation and melody, usually fronted by nylon-string guitar and fiddle.
* StepUpToTheMicrophone: Hopkins sings most of "It's Not OK" on their debut album, and Cook sings part of "Last but Not Least" on ''Uncaged''. The band has also done covers of "[[Music/TheWho Baba O'Riley]]" in concert with Brown and Cook alternating the lead.
* SubduedSection: They love this trope:
** The third verse of "Chicken Fried" has just nylon-string guitar.
** The final verse of "Colder Weather". A cappella for the first two lines, and just piano for the rest.
** The midsection of "Keep Me in Mind" goes into a slower tempo, with just piano and synthesized strings.
** The third verse of "All Alright" drops most of the instruments and slows down to a waltz before resuming the usual time signature and tempo.
* SubvertedRhymeEveryOccasion: Inverted in "Whiskey's Gone":
-->Well I stumble my way into my local bar
-->Where I saw the devil in my glass
-->The bartender told me it was time to go
-->I told him that he could lick my sack
* UncommonTime: "Heavy Is the Head" isn't entirely in 4/4; the chorus is in 6/8, there are measures of 2/4 and 3/4 sprinkled throughout, and most of the ending is in 7/8. Fittingly, the song features Music/ChrisCornell, better known for being in [[Music/{{Soundgarden}} another band]] that used many odd time signatures.
