Marshall Charloff taught himself to play the guitar at the age of 15 and later taught himself the piano, bass, and drums. He is a celebrated producer and recording artist, skills that paved the way for Marshmallow Fields, a production team consisting of Marshall, Grammy winner John Fields (The Jonas Brothers, Miley Cyrus, and Switchfoot) and Steven "Funkytown" Greenberg. Marshmallow Fields's credits include productions for Grammy Award winners The Commodores, Rock and Roll Hall of Fame inductees Little Anthony and the Imperials, and multi-platinum selling Lipps Inc. just to name a few. Marshall also wrote the song "Don't Rock It", which is on the Commodores XX album released in 1993.

In the 90s, a very young Marshall paired once again with John Fields to record and release an EP under their collaboration name of Marshmallow Fields. The single charted on the Billboard Top 100 dance charts and is still in rotation amongst DJs around the country. Although Charloff and Fields shared co-production credits, the release was executive produced by Steven Greenberg.

Marshall has played in the local scene in bands such as Boogie Wonderland, Westside, Saved By Zero and Star Fish. On the national platform, he has played rooms in Las Vegas including fronting the band Purple Reign (a Prince tribute) as a Prince impersonator.

Currently, Marshall performs as one of the country's most sought after dueling piano players and has paired up with equally in-demand Dan Satterberg to form The Funkeys. Charloff cut his teeth in this format seven years ago and hasn't looked back. Marshall incorporates his experience as one of the nation's best Prince impersonators in his Dueling Pianos show as well as his skills on other instruments to wow audiences and leave them wanting more.
