"This band is AMAZING! We had so many compliments from our guests about how fun the music was and we saw people on the dance floor that would normally stay seated. Their music just makes you want to dance!"

"[Emily Day is] deeply versed in standards from the 1920s and '30s, swinging gracefully through hits by Fats Waller, Jimmy McHugh and Irving Berlin (while also contributing pitch-perfect originals that sound like lost American Songbook standards)."                - Andy Gilbert, Albany Scanner
