Formed in New York City in 1999, the eclectic Jazz/Soul/Funk/Hip Hop/Fusion “big band” Burnt Sugar the Arkestra Chamber has showcased a rotating cast of varied musicians (who’ve worked with the likes of TV on the Radio, William Parker, Phish and many others) on 14 avant-garde recordings since its formation. Veteran Rolling Stone critic David Fricke once described the improv-heavy Arkestra as “a multiracial jam army that freestyles with cool telekinesis between the lustrous menace of Miles Davis’ On The Corner, the slash-and-om of 1970s King Crimson, and Jimi Hendrix’s moonwalk across the side three of Electric Ladyland.” The expansive ensemble will perform two sets at its Cincinnati tour stop, joined by special guest Napoleon Maddox, frontman for Cincinnati-based IsWhat?!. 10 p.m. Thursday. Free. MOTR Pub, 1345 Main St., Over-the-Rhine, motrpub.com.
