Pitches Be Crazy (also known as PBC) is a 5 person, all vocal cover band based out of Fort Washington, MD. Using no instruments or backing music, PBC creates all of the music vocally with the use of electronic effects processors to enhance the product. Although the music is created solely by the vocalist's voices, the use of effects processors creates a full-instrument band sound. With heavy percussion and sub-harmonic bass, PBC creates music similar to any other full-instrument band. Because of the diversity and backgrounds of the members, R&B and hip-hop artists from the 1970s thru 1990s heavily influence the music selection covered by the band. The goal of PBC in live performances is to create a "party" like atmosphere with recognizable, up-tempo, high-energy music.
