House music
Shortly after Mark became friends with Derrick Carter in 1988 at a record store in Chicago, he developed an interest in House music. Mark experimented with a deeper style, dropping De La Soul, disco classics and other styles not being played in the main rooms of nightclubs. While exploring purist forms of House Music, Mark developed his trademark style, known as "Mushroom Jazz": acid jazz infused with the West Coast's jazzy, organic productions along with urban beats.
