2) BEFORE CIVILIZATION
Scientific illustrator Laura Cunningham wraps up her exhibit, Before California — which imagines the natural Bay Area landscape before humans mucked it up, and which our art critic Alex Bigman described as “a terrifically illustrated textbook about the effect of human activity on local wildlife” — with a conversation with Ryan Phelan of the Long Now Foundation. At the David Brower Center; 6:30 p.m., free.
Tonight you’ll have the rare chance of seeing one of Hitchcock’s great films — North by Northwest, starring Cary Grant and Eva Marie Saint — on the big screen. At PFA, part of the museum’s ongoing Hitchcock series. 7 p.m., $9.50.
4) LA NATIVES

5) EXPERIMENTAL SOUNDS
If lush harmonies and pop melodies aren’t your thang, then head to Swarm Studios, where local musicians Rent Romus’ Life’s Blood project (featuring pianist Thollem McDonas) and Lewis Jordan (collaborating with Karl Evangelista’s Ai-Ai band) will interpret the music of free-jazz saxophonist Albert Ayler, part of the three-week Sound Salon. 8 p.m., $7-$10 sliding scale.
