Ian McDonald dies aged 75

Multi-instrumentalist and songwriter Ian McDonald, best known for his co-founding roles in both King Crimson and Foreigner, died Wednesday at the age of 75, AP reports. McDonald was known as one of the key architects of progressive rock, playing both saxophone and keyboards in King Crimson and co-writing its iconic 1969 debut, 'In the Court of the Crimson King'. The record’s opening track, '21st Century Schizoid Man', featured McDonald’s wild double-tracked alto-sax solo. Guardian describes him as "a galvanising force in the group’s potent mix". McDonald also co-founded rock outfit Foreigner with guitarist Mick Jones.
