Beginning on tenor saxophone while growing up on a small ranch in southeast Florida, Shelton switched to alto saxophone in college, as a way to focus on the classical techniques of the instrument. After college, Shelton lived in Washington DC for a summer where he met other young musicians interested in making music unrestricted by style. He moved to Chicago in the spring of 1999, inspired by the amount of musical activity and quickly became involved in the city’s creative music scene. While there, Shelton developed his playing style on alto saxophone while also studying clarinet and trumpet. He played creative jazz and improvised music in many settings, including the groups Dragons 1976, Arrive, and Rapid Croche. Over time he also became interested in the use of computer-based electronics for the live sampling and manipulation of acoustic instruments, and formed the group Grey Ghost with Johnathan Crawford.

After several productive years in Chicago, Shelton moved out west to study electroacoustic music at Mills College in Oakland, California. Shelton continues to focus on live improvisational-based music that uses both acoustic and electronic instruments. In California the groups Flockterkit, Ton Trio, Son of Gunnar Ton of Shel, the Shelton/Healy duo, the Pink Canoes, and Settled represent his music. He maintains his connections to Chicago through the groups Dragons 1976 (Multikulti), Arrive, Rolldown (482 Music), and Keefe Jackson’s Fast Citizens (Delmark).
