Amanda Palmer and Edward Ka-Spel

Bisexual Boston native Amanda Palmer has made a name for herself as performance artist and a musician (solo and as part of the Dresden Dolls, her dark cabaret duo). But now the frequently edgy, occasionally controversial indie rock darling has teamed up with another eccentric artist—Edward Ka-Spel, lead singer of trippy art-pop act the Legendary Pink Dots—for a full-length album. “I Can Spin a Rainbow,” out in May, distills state-of-the-world fears and anxieties into a set of simultaneously scary and hopeful songs. They’re supporting the record with a small tour, and theirs is definitely a collaboration that is worth catching live.
