The Count Basie Orchestra is a 16 to 18 piece big band, one of the most prominent jazz performing groups of the swing era, founded by Count Basie. The band survived the late-forties decline in big band popularity and went on to produce notable collaborations with singers such as Frank Sinatra and Ella Fitzgerald in the fifties and sixties. The group continues to perform and record even after Basie's death in 1984.
