Mike Campbell (guitarist for Tom Petty & the Heartbreakers) and local musician Jonathan Wilson will host the second annual holiday “jamathon.” They haven’t revealed yet who this year’s performers are, but if last year is any indication—Jackson Browne, Bob Weir, Jeff Lynne and Benmont Tench—it’s going to be two nights of memorable musical camaraderie. All proceeds from the concert will buy musical instruments for Manual Arts High School and medical care for furry friends from the Tazzy Animal Rescue Fund. More information
