Airs Thursday, August 30 at 8:00 p.m. Tune in for part two of a special featuring the 2010 Savannah Music Festival performance by a piano, guitar and reed trio featuring Dick Hyman, Howard Alden and Ken Peplowski. The term "piano trio" usually refers to to a group comprising a pianist, a double bass player and a drummer. The pianist is generally the leader of these trios, which are usually named after the pianist, such as the Bill Evans Trio or Oscar Peterson Trio. In 1937, however, Nat King Cole formed a piano-guitar-bass trio in Los Angeles, and it became the ensemble format that he would use for the remainder of his life, proving that you didn't need a drum kit to swing.
