Venues similar to Sweetwater Music Hall?

Hello,

we're going on a roadtrip from LA to Sausalito and as we love 70's music, we wanted to visit Sweetwater Music Hall in Mill Valley for some live music. We found out that on the night that we're gonna be staying in the area, there are no events unfortunately. SO I've been google-map searching for similar music venues (with 70's california rock/americana/alt-country type shows), throughout California and need some help. ANY suggestions around the SF area, PCH down to LA would be appreciated! Thanks!
