Spectrum is an Australian band from the early 1970's. Australian Spectrum was the brain-child of the eccentric song-writer Mike Rudd and his bassist mate, Bill Putt. They had limitted success commercially and remained an underground band. In the mid 70's they formed a more commercial unit called Indelible Murtceps (Spectrum spelt backwards) and often played a double set, one as Spectrum one as Murtceps.

Rudd and Putt went on to form another more commercially successful band, Ariel, in the late 70's.

Spectrum are best remembered by their one big hit - "I'll Be Gone", which has been covered by many Australian musicians including Chain and John Williamson.
