A stunning stoner metal bill at the Regent this week, as San Francisco sludge duo Black Cobra join up with San Diego psychedelic rockers Earthless, plus High Tone Son of a Bitch and Ape Machine to open for Brit band Orange Goblin. Ben Ward and his quartet have stayed pretty much intact since forming in 1995 — a rarity today. Last year they put out the The Wolf Bites Back album, their ninth in total and a more than respectable follow up to 2014’s Back From the Abyss. The band has always had solid Black Sabbath and Motorhead roots, though they’ve dabbled in punk and psychedelic sounds over the years. But whatever they do, they sound like Orange Goblin.

Orange Goblin, Black Cobra, Earthless, High Tone Son of a Bitch and Ape Machine play at 8 p.m. on Monday, September 2 at the Regent Theater.
