The Cosmo Alleycats at the Blue Note

The Blue Note presents the Cosmo Alleycats on Thursday, May 2, at 7:30 p.m. The Cosmo Alleycats have been a favorite of the San Francisco music scene since its beginning in 2010 for bringing a potent mix of swing and vintage dance music to the stage. Led by vocalist Emily Day, Cosmo Alleycats draws from several decades of American music, along with inspired originals. Blue Note, 1030 Main St., Napa, www.bluenotejazz.com/napa
