There’s a perfectly hummable sentiment somewhere in Friend Roulette’s “Sailing Song” that keeps working its way back to the surface, but only after first progressing through all manner of uneven meter changes, brass fanfare and incidental thematic adventure. At times stepping boldly into a space usually exclusive to the imagination of score composers like Danny Elfman, the group essentially writes baroque pop pieces for an imagined Brechtian musical, casting its talented singers/songwriters Julia Tepper and Matthew Meade as the show’s unlikely protagonists. They will be performing at Bushwick’s Delinquency next Friday (9.14). Meanwhile, read Mike Levine’s interview with the band here.
