On Tuesday, Nov. 20, legendary bassist George Porter Jr. will lead a gang of musicians at Mill Valley, Calif.’s Sweetwater Music Hall to benefit the Send It Foundation.

The list of featured musicians include Eddie Roberts of The New Mastersounds, Adam Deitch of Lettuce and Jennifer Hartswick of Trey Anastasio band as well as keyboardist Joe Tatton, horn-player Mike Ohimos and guitarist Benjamin Andrews.

According to the Sent It Foundation’s website, the nonprofit provides “outdoor adventures for young adults battling cancer.” It also preaches the message that “while none of us know what tomorrow holds, what we all have is today.”

Tickets for the event are available here.
