He developed skills in music and art under the direction of Eddie Allen, Sylvia Spicuzza, LeRoy Augustine, and Joe Ferrara within the Shorewood public school system. From 1972 to 1976, Hoffman concentrated on watercolor painting and drawing under professor Laurence Rathsack in the University of Wisconsin–Milwaukee (UWM) Fine Arts programs. He also played popular music with local bands at live music venues throughout Wisconsin. From 1977 to 1978, Hoffman studied graphic arts with Leon Travanti and graduated from UWM with a BA in fine art and visual communications.

He performs on the BoDeans 1986 debut album "Love & Hope & Sex & Dreams" (reissued in 2009 as a CD/DVD set). Hoffman performs in BoDeans videos for the songs "She's A Runaway" and "Fadeaway." He reunited with BoDeans singer/songwriter Sam Llanas to form the band Absinthe and released A Good Day To Die in 1998.
