From hip-hop to Haydn, if you’re looking for a cultural event in the San Francisco Bay Area, Hewlett Foundation grantees have you covered. Four online calendars catalog the bountiful arts scene by region – Artsopolis in the South Bay, 510Arts in the East Bay, SFArts in San Francisco, and Sonoma Arts to the north – and a fifth, San Francisco Classical Voice, covers classical music for them all. You can search by event type or date, and learn about classes and workshops, festivals, and outdoor events – even what’s free to do. San Francisco Classical Voice also has professional reviewers covering that music scene. Check an arts calendar this summer for your culture fix.
