I absolutely can't work in the studio without music and have done a ton of research about this. My faves range from Buddy Guy, the Stones, Harry Nilsson, Mozart, Puccini, Jonny Lang, Junior Wells, John Lee Hooker, Albert King, and just about every movie soundtrack worth listening to...art and sound are inextricably bound together. Some days, I may just play the same track over and over and over. Pythagoras understood the relationship between visual and musical composition and the human. I talk a little bit about it in my TEDxCalgary talk and the Community Fusion Project if you're most interested in my take on this.
