At the Foos' Los Angeles show on Monday, the rockers teamed with the Fleetwood Mac singer and the three-piece rock act for a pair of performances, beginning with the classic Fleetwood track "Gold Dust Woman."
But that wasn't all. After choosing something very much in Nicks' wheelhouse (she wrote it, after all), they moved into the '80s with the Tom Petty-penned, Nicks-performed "Stop Draggin' My Heart Around."
Nicks was situated on the right side of the stage, the sisters HAIM on the left, while Grohl, still atop his rock throne after his broken leg, straddled the middle. Nicks handled the lead vocals here with occasional Grohl interjections, as expected, but HAIM managed perfectly well on backup:
The Foos are in North America on tour behind newest album Sonic Highways until October, at which point they'll tour Europe through November.
