While pursuing his JD and MBA at Georgetown, he independently produced and distributed his first CD (Lessons in Love), which sold more than 40,000 units; a phenomenal success for an unknown independent artist’s debut release. This album helped him launch his career as a renowned jazz keyboardist/pianist, and later, he released his second CD (Inter Alia), with staggering success. This success caught the attention of Black Entertainment Television (BET) founder and businessman Robert L. Johnson, who invested and partnered with Marcus to establish Marimelj Entertainment Group. Under their partnership, MEG’s label Three Keys Music housed Studio 8121, a full-service recording studio, and two music publishing companies: Marimelj Music Publishing and Three Keys Music Publishing.
