After highlighting Monster Magnet’s melodic side and Stones-schooled roots on 2007’s 4-Way Diablo, Dave Wyndorf gets right to bruising business on Mastermind’s opener, “Hallucination Bomb,” where a sludgy bassline sets the stoner-rock steamroller in motion. Arriving two decades into his career, this album is a testament to Wyndorf’s undiminished swagger: “Gods and Punks” whips a maraca-spiced strut into a rousing statement of defiance, and “100 Million Miles” is a fierce floorboard cracker that romps and stomps like heavy-metal Motown.
