The first releases from Filthy Friends, the scorchingly melodic rock group whose membership consists of some of the most original musical voices of the past three decades, came as a small, delightful shock to the system. Not only because of the names associated with the project, including Sleater-Kinney co-founder Corin Tucker, R.E.M. guitarist Peter Buck and indie stalwarts Scott McCaughey and Kurt Bloch, but also because of how ably they were able to mesh their individual sounds into a crackling melodic whole on debut album Invitation.
