Singer-songwriter Jackson Browne may be known for his laid-back soft-rock sound (he’s a frequent collaborator with artists like the Eagles and Linda Ronstadt), but he’s been a social activist as long as he’s been a musician. Browne has been heavily involved in environmental, public health and foreign policy causes since the 1970s, from heading up a coalition of musicians against nuclear energy to singing about American intervention overseas. Even as he’s become a classic rock elder statesman (thanks to hits like “Doctor My Eyes,” “Running on Empty” and “Somebody’s Baby”), he’s remained politically outspoken, often lending his presence and music to benefits and rallies.

Like a lot of rockers from his generation (including Vegas regulars John Fogerty and Carlos Santana), Browne has been embraced in Vegas, and his three-night stand at The Venetian could be a sign of more to come. Browne isn’t settling into any late-career complacency, though. He recently combined songwriting and activism by recording the theme song for the AIDS documentary 5B, and he’s hard at work on material for a new album. “I’m pretty opinionated, of course, so that comes out in everything I do,” he told Billboard last month, and that’s exactly what fans love about him.

The Venetian, 8 p.m. Aug. 21 & 23-24, starting at $49.95 plus tax and fee. 702.414.9000
