Awesome possum. Win sauce. Other cliched hipster sayings.

Here we go.

COLOUR REVOLT is a Ghettotech band from Oxford, Missisippi. Similar to My Bloody Valentine/Mogwai in their dedication to depth of sound, the band works very well as a whole. The vocalist, however throws a wrench in the stereotype and sounds like he should be singing in a Pete Wentz band for fainting tweenage fangirls who love how "edgy" Hello Monday is. The band itself experiments a lot with homemade sonics/effects, and manages to pull off a rather low-key, Failure-esque guitar sound.

SHOWBREAD is raw rock at it's very best, basic, and harsh. Signed to Tooth & Nail Records and with too many band members to name, SB manages to somehow capture the energy that makes their genre good, translate it into wax, and then maintain it through even the crappiest sound system. There is nothing new about SB, their only downside is just how similar they sound to any other raw band at first listen, but with repetition the subtleties that make them SO different become apparent. Without a doubt, this the band that tops my list of "bands to see live before i become that creepy old dude at the rock show."

MERCURY REV is CSNY crossed with Kermit the Frog as a mad DJ remixing Venetian Snares, all blended in a large bowl made of the Sounds of Space radio show, and with a level two cups of Wayne Coyne chewing out the Arcade Fire. So, yeah. and as pretentious as that sounds, it's all true; check it out.

ALSO: it would be worth your time checking out the NOT ALONE RECORD label from Denver. They have signed to them Children Collide, Dine Alone, Time & Distance, and District Lines to name a few. All bands on the label are worth some listening, are really poppy, and are a great alternative to the Wentz harem of $$$ makers. Also, most of the bands are on Purevolume. (T&D was just featured on the homepage today, actually.)

Happy listening.
