From Variety:
Guitarist Cornell Dupree, one of the most prolific and talented session players in R&B and jazz, died May 8 in Fort Worth, Texas.
Dupree was 69 and had recently been diagnosed with chronic obstructive pulmonary disease.
Known as “Mr. 2500” (for the number of recording sessions on which he reputedly played) and “Uncle Funky,” Dupree established himself as a studio star at Atlantic Records in the ’60s. Over the years he cut freelance dates with Miles Davis, B.B. King, Ray Charles, Herbie Mann, James Brown and Jimmy Smith, to name just a handful of his most notable employers.
