Revivalist and traditionalist bands constantly put fresh twists and variations on old music, but the Carolina Chocolate Drops do something far more intriguing and inspiring. Rhiannon Giddens, Dom Flemons and Justin Robinson don’t approach the vintage black string music they perform like they’re dealing with treasured templates that require pristine, purist intepretations. Instead, they deconstruct, explore and tweak reels, mountain music, folk tunes and marches in the same manner the hip-hop generation strips away the harmonic complexity of hard bop and soul jazz and plays the verbal forays off the compositions’ rhythmic arrangements. Through their instrumental array that ranges from kazoos, jugs, harmonicas and guitars to animal bones and snare drums, the Drops make songs cut decades before they were on the earth sound inventive and spontaneous. It’s safe to say the old time fiddlers they idolize like Joe Thompson (who appeared on their 2009 release on Music Maker) probably never envisioned hearing his songs performed alongside a zany remake of Blu Cantrell’s “Hit’em Up Style (Oops!).” They’ll be doing pieces from their excellent current Nonesuch release Genuine Negro Jig and four other discs during their Tuesday show.
