He recorded his first solo album in 1971 on the Mainstream label, followed by two dates issued by Catalyst in 1976 and 1977, reissued in the superb collection “The Catalyst Years”.

He has also contributed to other dates by Todd Cochran, Don Ellis, Hampton Hawes, Azar Lawrence, Julian Priester, Freddie Hubbard, Eddie Henderson, Joe Henderson, Earl Hines, Bobby Hutcherson, Jon Hendricks, Earl Anderza, Patrice Rushen, and other jazz notable and fusion acts from the era.

Throughout the 1990s and 2000s, Caliman was active leading a quartet and quintet in the Seattle area, served on the music faculty at Cornish College of the Arts, and taught private lessons to area musicians. He died of liver cancer in September 2010, at the age of 78.
