CLUB: Come catch classical/electronic composer Mason Bates working his magic outside Carnegie Hall and Davies. He spins tonight in downtown SF along with sublime MarsBassMan (David Arend) on upright bass.

6 - 8 p.m. // Varnish Gallery (77 Natoma) // free

COMEDY: Local rib ticklers Hasan Minhaj, Ali Wong, Sal Calanni, Joe Tobin, Mark Lundholm, Reggie Steele, Nato Green, and Johnny Steele all try to make you pee your pants in an effort to land a spot on The Late Show at tonight's "The Late Show with David Letterman Auditions." (B.Y.O.B.)

9 p.m. // San Francisco Comedy College (414 Mason) // $15

FILM: This Sician thing must end! But not tonight because The Godfather and The Godfather II (winner of the the Best Picture Oscars in 1972 and 1974, respectively) will have you craving Chianti, bloodshed, and a pre-plastic-surgery-gone-awry Al Pacino when they both screen back-to-back in the Castro.

5 p.m. (I), 8:50 p.m. (II) // Castro Theatre (Castro & Market streets) // $10
