KeyStone is Philadelphia's new part-time professional six-voice contemporary a cappella group. When not on our day jobs, we perform pop rock songs, nothin' but mic. Booming bass, rocking beatboxing, and soaring vocals cover song of the last 50 years.

KeyStone is based in Southeast Pennsylvania. Formed in April of 2011, the six members of KeyStone have over 100 collective years of experience in vocal and theatrical performance. KeyStone strives to present innovative, original arrangements of pop and rock music both familiar and obscure. They also have a flair for quirky novelty numbers that get audiences laughing and smiling.

KeyStone is at home performing in both amplified and acoustical environments. The majority of their repertoire features a lead vocalist, background vocals and vocal instrumentals, vocal bass, and vocal percussion (beatbox). KeyStone uses a simple tech setup with six microphones, monitors, and mains with minimal compression and reverb.
