The flexi-sized Halifax combo played live shows for years, stoking curiosity about Eastern European melancholy and 1930s Parisian jazz, before hitting the studio. Now well into its recording career, Gypsophilia’s love of variations keeps the sound surging, well, forward like the label says. Muted trumpet, violin, acoustic bass and electric guitar veer off for solos and then meld into unique harmony throughout “Bir Hakem,” with its subtly descending hook. The title song rates a dub remix, for those who insist on modernity in their Old World echoes. Even as members come and go, the sense of adventure in Gypsophilia has never been stronger.
