Haim Days Are Gone is one of the top attractions scheduled to perform at that mammoth music event, which takes place over the next two weekends in Southern California. Further down the road, the group will return to the Bay Area in August to play the Outside Lands festival in San Francisco. Expect Haim to shine brightly in those high-profile settings, just like it did Wednesday, during the first of two sold-out shows at the Bay Area's most legendary rock hall. Backed by two musicians, the Haim sisters opened the show with a powerful version of "Falling," the lead track on "Days Are Gone." Danielle Haim stole the show, repeatedly, with fretboard fireworks that announced there's a new guitar hero in town. She's something else on the ax, delivering leads that recall Mike Campbell (of Tom Petty and the Heartbreakers) and so many other classic-rock icons.
