March 9. New York guitarist Mamie Minch is a stunning interpreter of prewar blues who vocally channels the ghosts of greats like Bessie Smith, Sarah Martin, and Memphis Minnie with eerie authority. Raised in the "Delaware Delta," she discovered the music through her father, who taught her the dazzling fingerstyle guitar technique she possesses via tunes by Mississippi John Hurt and the Reverend Gary Davis. After a couple years with all-female retro quartet the Roulette Sisters, Minch, who plays with her full band at MASS MoCA this month, toured Europe with an anarchist street band and busked around Manhattan. Her 2008 solo debut, The Razorburn Blues, is a stunner. (Le Ballets Jazz de Montreal dances in March 2; Balkan Beat Box bangs March 16). 8pm. $12, $16 ($10 students). North Adams, Massachusetts. (413) 662-2111; Massmoca.org.
