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 continued to perform and record as a 'ghost band' after Count Basie's death, and are currently under the leadership of Bill Hughes.
