Marcus Roberts (born August 7, 1963 in Jacksonville, Florida) is an American jazz pianist who has achieved fame as a stride pianist committed to celebrating classic standards and jazz traditions. Roberts has also distinguished his solos by accompanying himself with walking basslines. He thus creates a more two-fisted style than is found elsewhere in modern jazz, and his basslines are also convincingly spontaneous. Roberts interprets Thelonious Monk, bringin creative dissonances to Monk's compositions.
Marcus Roberts performs a Thelonious Monk tune called Ba-lue Bolivar Ba-lues-Are (aka Bolivar Blues).
