The Marcus King Band Greenville, SC Songwriter. Guitarist. Singer. Bandleader. At only 22 years of age, Marcus King has been writing songs, performing onstage for half his lifetime and fronting his own groups for nearly a decade. Since he was a teenager, he’s been trading licks with famous fans and mentors Warren Haynes and Derek Trucks. All five members of the band—drummer Jack Ryan, bass player Stephen Campbell, trumpeter/trombonist Justin Johnson, sax player Dean Mitchell and keyboard player DeShawn “D-Vibes” Alexander—create an expansive and dexterous musical unit that has honed their synergy through endless touring.
