Erin Birgy leads her band Mega Bog through a labyrinth of unusual sounds, mixing jazzy idylls with folk and atmospheric, psychedelic passages. The group’s latest album, Dolphine, is about the strange creatures who chose not to evolve as humans but instead remained underwater as dolphins. The theme is a launching point for Birgy’s own evolution as a person dealing with tragedy, set against a backdrop of political and environmental chaos on land. According to Birgy’s bio, “Dolphine is an album for the swimming human shadow obscured by waves.” Such glassy, intimate tracks as “I Hear You Listening (To the Bug on My Wall)” segue into the arty, baroque jazz-prog of “Left Door” and the austere, enigmatic folk of “Waiting in the Story.” Mega Bog open for the jazz-punk Fugazi spinoff The Messthetics.
