There's lots to do this weekend in addition to Noise Pop and the Oscars. Let's take a look!

Musicians Pay Tribute To Public Radio: Noise Pop presents a line-up of notable musicians on Saturday, including Thao, Zach Rogue, John Vanderslice, Kevin Johnson, Zoe Keating, Quinn DeVeaux, Sean Hayes, and Jhameel, who will converse with radio producer Stephanie Foo of NPR's Snap Judgment before a live audience about the importance of public radio as a vital platform for independent music. The event will also feature live music and will later be broadcast on KQED and KALW.

Punk Swap Meet: Spike your hair, sell or trade records, zines, tapes, and other crafts at the Speakeasy Brewery on Saturday. You're also invited to make a mix tape and swap it with others and DJs Kirka Sherpa, Güera, Tö-Far, and JoNeric will be spinning tunes.

Bookfest: Get a chance to rub elbows with Joyce Carol Oates, Saul Bellow, Philip Levine, and other acclaimed writers at The Jewish Community Center's Bookfest on Sunday.

SF Flea: Head down to Fort Mason all weekend for some sweet deals at this semi-annual "fresh, modern public mart attracting an inspiring blend of local design, style, food, art, and entertainment." Ticket proceeds benefit ECO SF.

Discovery Day: The Arts Commission Gallery is hosting a day of science and art on Saturday in partnership with Science@Cal as part of its current exhibition, Vast and Undetectable. Local scientists will be giving presentations and answering questions, activity booths will be set up for the little ones, and at 3 p.m., participants are invited to go on The Faux Floe Tour, a five minute excursion into the invasive synthetic rhizomatic world made visible by Reenie Charrière, available in both English and French.
