DMX Krew is Ed Upton, a DJ/producer who has recorded for Aphex Twin's Rephlex Records, Adult.'s Ersatz Audio, International Deejay Gigolos, and his own Breakin' Records. Upton's productions update classic breakdance-ready electro with modern tweaks and tricks. He's a prolific producer, releasing a half dozen albums and numerous singles over the past decade, and his recent Roller-Rink Boogaloo Mix (available for free download along with some live DMX sets at www.durftal.com/music/edmx/index.html) proves him to be a knowledgeable and tasteful selector. This rare live set in Portland is his only Northwest appearance, and if you're looking to escape Bumbershoot, it'll be well worth the drive.
