Indelible Murtceps

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.

The Indelible Murtceps' debut single, "Esmeralda", was issued in 1972, which peaked in the Go-Set National Top 40. It appeared ahead of their studio album, Warts Up Your Nose(1973), in the following year, which made the top 20. Sometimes both groups shared a stage; both disbanded after a joint final gig at the Dallas Brooks Hall on 15 April 1973. The performance was included on a shared live double album, Terminal Buzz (1973), which appeared in December that year.
