Frank Rosolino was an American jazz trombonist, born in Detroit, Michigan. He performed with the big bands of Bob Chester, Glen Gray, Tony Pastor, Herbie Fields and Gene Krupa.  After a period with Stan Kenton, he settled in Los Angeles, where he performed with Howard Rumsey's Lighthouse All-Stars (1954–1960) in Hermosa Beach. Throughout the 1960s and 1970s, between nightclub engagements, Rosolino was active in many Los Angeles recording studios where he performed with such notables as Frank Sinatra, Sarah Vaughan, Tony Bennett, Peggy Lee, Mel Tormé, Michel Legrand, and Quincy Jones. In the mid-to-late 1960s he and fellow trombonist Mike Barone, billed as "Trombones Unlimited," recorded for Liberty Records several albums of pop-style arrangements of contemporary hits. He was a regular on The Steve Allen Show and a guest artist on The Tonight Show and The Merv Griffin Show. Rosolino was a talented vocalist, renowned for his distinctive form of scat-singing. During the 1970s, Rosolino performed and toured with the Grammy Award winning group Supersax.
