I started writing about DDAT and realized that they truly do defy description. What they produce totally destroys listener’s perceptions about the nature of genre boundaries. They also do wonders in the process of deconstructing musical and artistic forms and rebuilding them in new, challenging sound-shapes. The incorporation of hip-hop and jazz into the quartet’s output is particularly piquant, physically and philosophically. If such a melding of essential opposites is possible than DDAT—Chris Bidtah (vocals), Delbert Anderson (trumpet), Nicholas Lucero (drums) and Mike McCluhan (bass)—is likely the responsible artistic entity. The ensemble has their CD release party on Sunday, April 29, at the Cooperage (7720 Lomas Blvd. NE) and it’s worth noting that this concert is brought to grateful local listeners by AMP Concerts, which continues to make programming choices that make us smile over here in an office otherwise dominated by heavy metal relics and indie inclinations. 7:30pm • $15 in advance, $20 day of show • 21+ without parent or guardian.
