The Burlington-based folk trio Emma Cook & Questionable Company has a mythic origin story; co-creators Andy Feltus and Max Guyton began playing music together as roommates at the University of Vermont, and later met Emma — with whom Andy fell in love. The trio played their first show together on Halloween in 2012, and have been an unstoppable force ever since. Yesterday, the trio released their newest single “You Know Why” (streaming below), a jazzy folk track that leverages Emma’s incomparably smooth vocals to create something that sounds close to magic. Their next show will be at ArtsRiot in Burlington on August 9. – Lilly Milman, photo by Kayhl Cooper
