The refreshingly old-fashioned Cosmo Alleycats present "Old Sweet Songs", a show celebrating enduring melodies, a bygone style of songwriting, and original songs that contend for placement in the Great American Canon.   The group, Led by jazz vocalist Emily Day, “one of the major singers in her field” (Scott Yanow), endears audiences with their inviting musicality and playful improvisation, making quick converts of the jazz-curious, while still nodding to the serious aficionados.   Cosmo Alleycats have been a favorite of the San Francisco music scene since the band’s 2010 beginning, bringing to the stage a potent mix of swing and vintage music with a dynamic, soulful delivery. Led by vocalist Emily Day (“one of the major singers in her field” – Scott Yanow), Cosmo Alleycats draws from several decades of exhilarating American music, along with inspired originals, to deliver a fun and engaging performance. With sixteen years’ experience performing together, Cosmo Alleycats is a well-oiled machine. But however polished their performance may be, it’s the sense of playfulness in their improvisation that holds the door open for the unexpected.   "Emily Day opens a portal into a bygone era of torch singers and chanteuse elegance. Hints of Judy Garland and Ella Fitzgerald emerge as Emily and her Cosmo Alleycats charm their listeners throughout a tightly woven program of classic repertoire and carefully crafted originals. Audiences are beckoned ... to ponder, smile, and laugh in Emily's world, where the old glows new again."
