Later, he moved to Hollywood and studied audio engineering and jazz improvisation at Musician's Institute. He currently resides in Sherman Oaks, Calif., where he operates a Pro Tools-equipped recording studio that has resulted in state-of-the-art production.
Singletary's skills have been reviewed by music columnist Dan Berthiaume: "Jazzy keyboards in the style of Doors legend Ray Manzarek ... and futuristic sound effects provided by instruments such as the theremin also pop up, and Singletary still can't help but let what appears to be his natural optimism shine." And music journalist Jim Pasinski wrote, "Marcus is a workhorse, handling all the vocals, guitars, organs, keyboard and synthesizer ... [drawing] upon the Classic Rock sound of the ‘70s, while incorporating some of today's topics within the lyrics."
Singletary’s career highlights include six appearances on the Argentina-based radio show De Rock yFreud, two performances on Chic-a-Go-Go, which is a Chicago-based children's TV program,andseveral live showcases at L.A. venues, including the Henry Fonda Theater, House of Blues, Viper Room and Whisky a Go-Go.
