Timed to coincide with a season that keeps locals in town and out-of-towners away, the Doomtree hip-hop crew's annual Blowout at First Avenue is an alternative-rap fan's dream on the cheap, and just for us: eight-odd vital performers (rappers, singers, DJs) all worth seeing solo and even better in combination, where their Marx Brothers energy takes hold. Expanding to two nights this time, these shows cap a particularly heady year for Doomtree, which is saying something: 2010 marked their first major national tour as a crew, and brought a string of essential and expansive releases: Lazerbeak's synth-pop debut (Legend Recognize Legend), Paper Tiger's instrumental hip-hop opus (Made Like Us), and Dessa's assured mixture of lithe singing and meaty rapping on her own full-length solo album (A Badly Broken Code), plus a hot new single from Sims available at the show. Other performers include P.O.S., Cecil Otter, and Mike Mictlan. 21+ Friday; all ages Saturday.
Fri., Dec. 10, 8 p.m.; Sat., Dec. 11, 6 p.m., 2010
