September 1969
Concerto For Group And Orchestra
People involved
Ritchie Blackmore (gtr); Ian Gillan (vcl); Roger Glover (bss); Jon Lord (org/pno/kbr); Ian Paice (drm); and the Royal Philharmonic Orchestra conducted by Malcolm Arnold.
Lord's Concerto was performed live at the Royal Albert Hall on 24 September 1969, by Deep Purple (with two brand new members, Gillan and Glover) and the RPO conducted by Malcolm Arnold. The event was televized (in the UK and Denmark), recorded and released on both album and video (slightly edited). It gave Deep Purple a huge marketing.
