A special evening is in store as Seattle musician and historian Kurt Armbruster and the New Orleans host a celebration of Seattle's musical heritage as chronicled in his big new book, Before Seattle Rocked: A City and Its Music (University of Washington Press). The night here begins informally with a booksigning and conversation, then moves to a planned sequence to include the Olde Seattle Rhythm Band at 8, Overton Berry on piano at 9, and Alice Stuart and the Formerlys at 10. This should be fun. Cover charge for the music program is $8. The New Orleans Creole Restaurant is at 114 First Avenue South in Pioneer Square.
