Aarhus Jazz Festival 2015 · Tribute to Thelonious Monk. Thelonious Sphere Monk (1917-1982) was an American jazz pianist and composer. Monk had a unique improvisational style and made numerous contributions to the standard jazz repertoire, including “‘Round Midnight,” “Blue Monk,” “Ruby, My Dear,” “In Walked Bud,” and “Well, You Needn’t”.
His compositions and improvisations feature dissonances and angular melodic twists, and are consistent with Monk’s unorthodox approach to the piano, which combined a highly percussive attack with abrupt, dramatic use of silences and hesitations. He was renowned for his distinctive style in suits, hats, and sunglasses. From Wikipedia.
