Invitation is the debut album by Filthy Friends, the new supergroup from Corin Tucker (Sleater-Kinney), Peter Buck (R.E.M.), Kurt Bloch (The Fastbacks), Scott McCaughey (Young Fresh Fellows, The Minus 5) and Bill Rieflin (King Crimson). The 12-song collection works through a flurry of different moods and styles, genre exercises and joyous experiments.
