Here's another great heads-up from funcheapSF.com. The San Francisco Chamber Orchestra will be performing free concerts in downtown San Francisco, Berkeley, and Palo Alto this weekend.

The concerts feature Anja Strauss, soprano, Peter Lemberg, oboe, and Tod Brody, flute.

The two downtown San Francsico shows will be on Thursday at Liuli Gallery at 5:30 p.m. (Rush Hour Concert) and on Friday at Herbst Theater at 8 p.m. The Palo Alto performance will be at St. Mark’s Episcopal Church on Saturday night at 8 p.m., and the Berkeley show is at the First Congregational Church on Sunday at 3 p.m.

All performances will have a 30-minute pre-show talk. SFCO members get reserved seating at all of the performances.
