Robbie Williams is releasing Under The Radar Vol. 1, an album comprised of B-sides, demos and unreleased tracks, exclusively via his website on December 8. Today (December 2), he unveiled the eye-popping nude cover art — that’s his butt! — and the LP’s tracklist. The cheeky Brit also shared a new track called “Bully”, which is considerably darker than radio-friendly hits like “Rock DJ” and “Angels”.
