The Bay Area is well known for a lot of things. One is the local music scene. Music venues close every day. Bands break up.
DJs move away.
Yes, the scene has a lifecycle, and it grows and fades. But it's survived a lot worse than this year's latest calamity. There is still plenty of music out there to check out, and much of it was bred right here. Do your part by supporting new music. There are lots of choice shows to go out and see.
