EMILY DAY
Jazz Vocalist - Band Leader
EMILY DAY
Jazz vocalist, arranger and songwriter Emily Day has been performing jazz since the age of 16. As “one of the major singers in her field” (Scott Yanow, Syncopated Times), Emily's voice carries the history of American music. On stage, she combines her deep knowledge of jazz with her whiskey-tinged timber and vocal acrobatics — simultaneously wild and precise.
She currently leads the San Francisco-based swing band Cosmo Alleycats, a group that celebrates the Great American Songbook and the bygone style of songwriting endemic to it.
​
Before relocating to San Francisco in 2012, Emily taught for several years at New England colleges and Universities. She holds a BFA in Jazz Voice from The New School in New York and an MA in Popular Music Studies from the University of Liverpool in England.
