Sha-Boom is a vocal trio who sing both acapella and with musical accompaniment. They perform Doo-wop standards and hits from the 50s to the 70s, but make no mistake, this is no mere nostalgia act. The joy, energy, and experience they bring to their music makes these songs as vital, powerful, and exciting as they were when you heard them for the first time. If this is history, then New York pizza is just bread with cheese and sauce.
