The name 'murtceps' is 'spectrum' spelled backwards. The Melbourne-based group developed an extensive repertoire of original experimental progressive rock music, intended for performance in a serious concert setting, using a large PA system and light show, as well as on occasion being augmented by Melbourne performance troupe 'The Tribe'."@en .
