They call me the Slippery Matthew Castle. Or at least they do aboard the Cosmic Lung, an intergalactic concert hall overseen by a brainstem in a cloak voiced by Jason Schwartzman. Impressively, this is one of the more rote happenings in The Artful Escape, a quest that also takes in astral highways, rock-powered butterflies and - steel yourself - a passive aggressive skiffle group.
