High Quality Content by WIKIPEDIA articles! Jon Douglas Lord (born 9 June 1941) is an English composer, Hammond organ and piano player. Lord is recognised for his Hammond organ blues-rock sound and for his pioneering work in fusing rock and classical or baroque forms. He has most famously been a member of Deep Purple, as well as of Whitesnake, Paice, Ashton & Lord, The Artwoods and Flower Pot Men. He has worked with numerous other artists including Graham Bonnet (following Bonnet's departure from Rainbow). In 1968, Lord co-founded Deep Purple. He and drummer Ian Paice were the only constant band members during the band's existence from 1968 to 1976 and from when they reformed in 1984 until Lord's retirement in 2002. One of his finest works was his composition Concerto for Group and Orchestra, which was performed at the Royal Albert Hall in 1969 with Deep Purple (Lord and Paice with guitarist Ritchie Blackmore, singer Ian Gillan and bassist Roger Glover) and the Royal PhilharmonicOrchestra.
