Re: Who played the drums on Daft Punk's "Giorgio by Moroder"?
Via Wikipedia (http://en.wikipedia.org/wiki/Random_Access_Memories):
Daft Punk conveyed their ideas to the musicians via sheet music and in some instances by humming melodies. Bangalter recalled an example in which he hummed a complex drum and bass line to Omar Hakim, who replicated and improved upon it for the track "Giorgio by Moroder".
Practice, Improve, Repeat...
