One of the original innovators in Chicago house, Marshall Jefferson had a hand in several of the music's most influential early tracks during the mid-'80s, particularly "Move Your Body," Phuture's "Acid Tracks," and Ce Ce Rogers' "Someday." As the acid house sound took over clubland, he moved into a more spiritual form of music later termed deep house; along with Larry Heard, he became one of its best producers. A reflective full-length titled Day of the Onion was released in 1996, and the trippy single "Mushrooms" (with Noosa Heads) appeared in its original form the same year, gradually becoming one of Jefferson's biggest tracks. He released several mixed compilations, mainly retrospectives of the genre and its roots, including 2003's Move Your Body: The Evolution of Chicago House. He's consistently stayed active, touring and releasing singles into the 2020s, including reunions with longtime associates Ten City and Curtis McClain.
