- Formed in the early-1970s at West Chester State University in Pennsylvania, the group started out as a progressive Christian rock band. Over time, the band's sound evolved toward jazz-pop and all of its releases featured at least one a cappella performance. In 1988, the group issued an all a cappella album that proved to be very popular. Subsequently, the group began alternating between a cappella and band albums and now usually performs a cappella Christian music.
