The Indelible Murtceps were an Australian progressive rock and dance-pop band, which formed, as a side project of Spectrum, in October 1971. Sometimes referred to as the shortened name, Murtceps, they were "a stripped-back version... [that] could play anywhere and often." They worked the more lucrative dance and pub rock circuit. Whereas Spectrum performed in a full concert setting, commonly at larger venues, like the T.F. Much Ballroom, and at rock festivals. From Wikipedia →
