The Meowstro Sings — Guster’s Keep It Together is an album created by the band Guster. It features all but one of the tracks from their release Keep It Together, with the vocals replaced by simulated cat meows. According to the band, the meows were sung by Guster’s monitor engineer at the time, Matt Peskie. The tracks were then released to Kazaa, in an effort to deter downloading of legitimate tracks.
