Mira Billotte's psychedelic folk band White Magic make albums that are full of prayers. The god she is praying to is unspecified, but it doesn't matter. Her voice—heavy and thick and dramatic and revelatory—would appeal to any deity. When I listen to last year's Dat Rosa Mel Apibus, all I can think of is the color purple. I hope there's a fog machine going when they play, and I hope they bring the sitar. With local folk wackjob PWRFL Power and Johanna Kunin. (Nectar Lounge, 412 N 36th St, 632-2020. 8 pm, $8 adv, 21+.)
