Robert Fripp indeed. Obscure to many, but I’ll never forget seeing him in the early 80’s incarnation of King Crimson touring for the Discipline album. Masterful.
Believe it or not Fripp was also a huge influence on the genres like House/Trance/Drum and Bass and other forms of electronica. His stuff is just so ‘out there’ that it impresses on a sheer “what the hell just happened’ level. The whole ‘soundscape’ thing he does is pretty wild. He certainly had his own ideas of what ‘music’ is supposed to be.
