Asteroid Cafe in Freemont on Thursday nights 9:30 to 1. Hammond B3, bass and drums.
The Ugly Mug in Ranier Beach on 1st and 3rd Sunday nights of the month, 7-10. Guitar and bass. I go to this one. PM me if you want for here.
Imo the standard is higher at the Asteroid but the Ugly Mug is more inclusive and friendly for Late Bloomers.
