After the Serious Moonlight Tour, Slick contributed to Box of Frogs' eponymous album and Game Theory's "Distortion" EP. At that time, Slick co-founded Phantom, Rocker & Slick with Slim Jim Phantom and Lee Rocker. The band released two records, "Phantom, Rocker & Slick" and "Cover Girl". Rolling Stones' guitarist Keith Richards contributed a performance to the single "My Mistake" - an experience Slick cites as one of the most memorable in his career. Between the two Phantom, Rocker & Slick albums, Slick appeared with Carl Perkins and a host of other musicians including Eric Clapton, George Harrison, Ringo Starr, and Rosanne Cash for 1985's "".
