Dave Sperandio, or "dio" as he is sometimes called, has been working with a cappella music for more than 15 years as a performer, producer, and engineer, and his work has appeared on scores of CDs for clients from around the globe.

Since founding diovoce in 2000, his clients have appeared on numerous "best-of" compilations, including over 30 appearances on the BOCA, CAMO, Voices Only, and 'Sing' series. Dave's work has received dozens of CARA nods, both as a performer and while "behind the glass". He is also the founder of the Alliance for A Cappella Initiatives, and the creator of the hit SoJam A Cappella Festival, now in it's 6th year, as well as the internationally acclaimed 'Sing' vocal compilation CD.

Dave has performed with numerous concert and symphonic choirs, acted as Music Director for the UNC Clef Hangers, toured the country with Atlanta-based vocal tonic, and currently performs with CARA-winning vocal sensation transit.

Most recently Dave partnered with fellow producers James Gammon, Tat Tong, and James Cannon to form VocalSource, which represents the largest and most comprehensive network of vocal music studios in the world.
