Thelonious Monk, Vastly Unique Jazz Pianist and Composer, 8x10 - Easy Digital Download!

From Wikipedia:

"Monk's compositions and improvisations feature dissonances and angular melodic twists, often using flat ninths, flat fifths, unexpected chromatic notes together, low bass notes and stride, and fast whole tone runs, combining a highly percussive attack with abrupt, dramatic use of switched key releases, silences, and hesitations."

Notable works include: Well, You Needn't; Straight, No Chaser; Blue Monk; and In Walked Bud.
