The pianist Geri Allen is one of the most celebrated jazz musicians of her generation. A Guggenheim Fellow and University of Pittsburgh Director of Jazz Studies, she has worked with a Who’s Who of players and arrangers, from Ornette Coleman and Charlie Haden to Laurie Anderson and Betty Carter. She has wrestled with Monk’s music throughout her career, examining his impossible sense of time in her splendid interpretations of “’Round Midnight,” for instance, and directing the Mary Lou Williams Collective, an ensemble devoted to the music of the late undersung composer, Monk confidant, and Duke professor. Allen is particularly well suited to take on the Monk canon. ### For a decade now, tenor saxophonist JD Allen has anchored his eponymous trio, supported by drummer Rudy Royston and bassist Gregg August. Allen’s ragged, searching tone is redolent of jazz’s blues heritage, and his playing reflects his pedigree as a grandson of the Delta, a son of Detroit, and a leader of modern jazz. The New York Times praised Allen’s “fearless approach to a formidable tradition.” At Duke Performances, Allen, Royston, August, and their guests will test and stretch Monk’s music in two sets each night, fearlessly facing one of the most formidable catalogues in jazz.
