To Do: Barlow, Trillin, Walken

· Music round-up: The Submarines at the Echo (free); Lou Barlow at Safari Sam's; The Starlite Desperation at the Viper Room; The Broken West at Spaceland (also free).
· The New Yorker's Calvin Trillin discusses and signs About Alice, his tribute to his deceased wife and muse, at Vroman's in Pasadena.
· Join in a joyous celebration of one of America's most auditorially recognizable actors at All About Walken: The Impersonators of Christopher Walken at the Paul Gleason Theater. Warning: We can't guarantee you won't hear the phrase "more cowbell" many more times than you might like.
