Michal Levy is "a designer, a musician, a filmmaker, and a bandleader" who has made a couple music visualizations. She seems to be a synaesthete who visualizes music in terms of shapes and colors, and experiences visual art as sounds. I really like the animation of large-ensemble jazz by Jason Lindner, especially after it leaves its cityscape; be sure to visit her site to see Coltrane's "Giant Steps" (it's on YouTube, but it did not play smoothly and ruined the effect.) (And, yes, we've seen Giant Steps animated before!)
