KeyStone is Philadelphia’s new semi-professional six-voice contemporary a cappella group. When not on our day jobs,  we perform pop rock songs,  nothin’  but mic. Booming bass,  rockin’ beat boxing,  and soaring vocals covering popular music of the last 50 years. We are available for all kinds of events,  from corporate to private,  educational to recreational.

What the pros are saying about KeyStone:

Barry Carl (Rockapella): “Very pro. Great dynamics and musicality. Great bass and percussion work. How many modulations were in that song?”

Tom Anderson (Random Notes, LLC): “Y’all need to hear this group @KeyStoneVocals from Philly. They’re not on the radar yet but give them a minute. Wow.  They were three for three on great soloists. Great arrangements sung well.”

Amy Engelhardt (The Bobs): “KeyStone is going to interesting places in their arrangements and choice of material.”
