"Keefe Jackson, saxophonist/clarinetist/improvisor/composer, arrived in Chicago in 2001 from his native Fayettevile, Arkansas. He performs regularly in the U.S. and in Europe with many musicians including Pandelis Karayorgis, Tomeka Reid, Tim Daisy, Dave Rempis, Jeb Bishop, Jason Roebke, Jason Adasiewicz, Mike Reed, Jason Stein, Josh Berman, Fred Lonberg-Holm, Frank Rosaly, Oscar Jan Hoogland and Marc Unternaehrer. He has also appeared with Michael Moore, Ab Baars, Michiel Braam, Satoko Fujii, and Anthony Coleman. Bill Meyer (Chicago Reader): "...the impeccable logic of his lines and the richness of his tone leave you wanting more... Jackson's high-register squiggles and coarsely voiced, rippling runs push the limits of the tenor's tonal envelope." Frank van Herk, de Volkskrant (Amsterdam): "[Jackson] has an old-fashioned, warm-woolly sound, and a feeling for melodic lines that take their time in unfolding." He has been mentioned in the DownBeat Critics Poll in the Rising Star Tenor Saxophone category. Recordings are available on Delmark and Clean Feed Records."
