Have you ever heard a piece of music and thought to yourself, "It sounds as though it's always existed." You might get that impression Thursday evening at 7:30 p.m. at the Ted Mann Hall, when mezzo-soprano Adriana Zabala and composer/performer, Gregg Kallor perform a song recital of works composed in collaboration. The two recorded many of these pieces several years ago. Both Zabala and Kallor spoke to Steve Staruch.
