American composer/musician, best known for being one of the co-founders of Devo. After that, he went on to score various television shows (Rugrats, Beakman's World, Sliders), films (Happy Gilmore, Rushmore), video games (The Sims 2, the Jak and Daxter and Crash Bandicoot series), and even commercials (that annoying jingle in the "Get a Mac"/"I'm a Mac and I'm a PC" ads).
He also has a great interest in drawing and painting, and currently hosts the drawing segment Mark's Magic Pictures, on Yo Gabba Gabba. His art tours regularly, including a show of the hand-painted postcards he sent to friends and family during his years on tour, a series of antique photos mirror-imaged to create the titular "beautiful mutants", and a series of paintings turned into rugs.
