The tapes were made between December 1979 and March 1981, and offer a range of glimpses into the band's development, including the moment Rhoads received and first tried out his effects pedal board.

The bassist, who hopes one day to release what he calls his "Holy Grail" tapes, launched the clips to mark the 32nd anniversary of Rhoads' death - and he's also taken the opportunity to illustrate how hectic life was in the band, especially once manager Don Arden appointed his daughter Sharon as tour coordinator.
