In 1938, Caceres became a member of Bobby Hackett's band, then worked as a sideman with Jack Teagarden in 1939 and Glenn Miller's orchestra from February 1940 to September 1942. While with Miller, he made an appearance in the films Sun Valley Serenade (1941) and Orchestra Wives (1942). Periods with Benny Goodman, Woody Herman, and Tommy Dorsey followed later in the 1940s.
