"It comes at you like a near-lethal cocktail of whiskey and adrenaline, looking both to the Seventies and light-years in the future. Not many bands have the audacity to begin an album with a solo and stretch its parent track to seven-and-a-half minutes long these days, but then again not many bands are like Comets On Fire. Even in Avatar's first minute you could reference the riffs of Black Sabbath; the unhinged, masculine energy of Led Zeppelin; and the brain-melting freeform combustions of Acid Mothers Temple. Yet even these comparisons sell the quintet short: where the previous bands have carved a niche, Comets On Fire have blurred and burned the lines so that they cover each other easily and unknowingly. Avatar may not be as intense or as out-of-loop as expected, but its otherworldy mix of prog-rock and freeform more than lives up to the expectations formed in the wake of 2004's Blue Cathedral."
"Part psychedelic jam band, part sub-Sonic Youth avant-rock skull–shredders, Comets On Fire’s previous trio of albums have displayed a gradual ratcheting up of quality. Their freeform freakouts have increasingly been given shape and purpose, especially after second guitarist (and Six Organs Of Admittance mainstay) Ben Chasny joined in 2003. Avatar is their most three-dimensional sounding record to date. Standout track, "Jaybird", is all jazzy chordal inflections, airy harmonies and skittering drums which briefly threatens to become The Byrds’ "Eight Miles High" before sliding into a bruising refrain that sounds like '60s acid-rockers Iron Butterfly."
