Karl Jenkins (1944-) a Welsh composer studied music at Cardiff University before finishing his musical education at the Royal Academy of Music, London. Jenkins initially made his mark in the "Jazz Polls" of the 1960s and 1970s when he co-founded the group Nucleus. Regularly playing at the famous Ronnie Scott's Jazz Club, the group went on to record three albums and win first prize at the Montreux Jazz Festival. However, his classical work Adiemus, which was commissioned for a television commercial, topped the classical charts around the globe and brought him to the world's attention. Jenkins has won many awards and with his concerts he has achieved critical acclaim. His double harp concerto Over The Stone was commissioned in 2002 for the Royal Harpist, Catrin Finch and Elinor Bennett accompanied by the BBC National Orchestra of Wales, and his concertante Quirk, commissioned by the London Symphony Orchestra and conducted by Sir Colin Davies, was premiered in 2005.
