The Panic Room

If you've been singing your entire life and matriculate at Tufts University, you will inevitably be kidnapped recruited to sing in a cult an a cappella group. That’s what happened to Ed. After five years (some of us need a little more time to graduate, OK?) he’d directed both the Tufts Beelzebubs and the Hyannis Sound, helping both groups record award-winning albums. He’d also received a degree in Vocal Performance from the New England Conservatory of Music, where he refined his voice and sang with several classical and jazz ensembles. Unable to escape the ironclad grip of the master we call a cappella, Ed has continued to arrange for and record groups around the country, earning recognition from CARA, RARB, BOCA, Sing, Voices Only, and his mother.
