The progenitors of the genre are nearly all from Washington state, and in fact grunge was also referred to as "The Seattle Sound", but if one uses that as a metric then both L7 and Stone Temple Pilots don't get included, which would upset many to the point of pitchforks and torches. Another interesting thing about the genre, if that's what we're calling it, is that none of the people credited with it wanted any ownership of the word. Punk bands proudly call themselves such. Not the case with grunge.
Frontman Robert Roth, the least known member, was actually very well known in Seattle's grunge community of the early 1990s. He was considered to join Nirvana when the band began seeking a second guitarist. Roth's voice actually brings to min
d Kurt Cobain during his most somber moments, and the nasal screeching of Mark Arm from Mudhoney when he screams. His guitar sound is incredibly dense and distorted but without sacrificing melody. Where Truly TRULY stands out is their incorporation of 60's sounds and song styles. "If You Don't Let It Die" almost sounds like The Kinks if they'd been a strung-out Seattle band in the 90s. A Rhodes piano featured on "Angelhead" lends a Doors-esque quality to the song's stoned feeling, not to leave out the use of a mellotron in the song's chorus, harkening to "Strawberry Fields Forever" (Roth would later earn mellotron credits on Built To Spill's Perfect From Now On).
Make no mistake however. While the songs on "Fast Stories... from Kid Coma" all have a psychedelic 60's vibe, the bulk of the sound is firmly rooted in punchy distorted rock music more akin to plaid shirts than paisley bellbottoms. This was producer Adam Kasper's first produced record... his other credits include heavier bands like Soundgarden and Queens of the Stone Age... and he would later go on to winning a grammy for Foo Fighters "There Is Nothing Else to Lose".
