"Joe Barbarotta has been playing bass for over forty years while he was waiting for technology to catch up to the sounds he was hearing in his head. Well, most of the sounds anyway. About ten years ago he picked upa seven string bass guitar in a store and was instantly hooked.Finally, with the ease of digital recording and the ability to play AS A BASS PLAYER in a tonal range formerly reserved only for guitarists and dolphins, "Bass Negligence" became a possibility. It's a bass album for sure but it explores the ability of an extended range bass instrument to be both a compositional and a solo voice "
