Fresh from their graduation ceremony at Yale this past spring, the new-to-Brooklyn trio Plume Giant is hitting the road in support of their full-length album “Callithump.” The record comes after an eponymous EP in 2010, and shows off the band’s jovial fusion of folk and fiddle, highlighting playful harmonies with their male-female vocals combination. “Callithump” was recorded over an 11-month stretch around tour and exam schedules, and will be released on August 28, with a US tour to follow. Fellow local folkies Tall Tall Trees will join Plume Giant for their record release show at the Mercury Lounge on August 31. – Devon Antonetti
