Trombonist Frank Rosolino was one of the bright lights of L.A.'s Cool jazz scene of the 1950s and '60s. He cut a series of great sides with the Stan Kenton Orchestra during the early '50s, and went on to record frequently through the rest of that decade with the hot, ever-shifting jam session group known as the Lighthouse All-Stars. Rosolino's seamless style meshed perfectly in Swing, Cool, or Hard Bop sessions, and he could say as much in a short solo as in an extended one -- a quality that made him a favorite session player with everyone from June Christy to Dizzy Gillespie to Horace Silver. Famed for being a jokester, he shocked his fellow musicians when he killed his two young sons before committing suicide in 1978. The feeling of confusion and betrayal felt by his friends and peers over this sickening crime has been authoritatively covered by jazz writer and lyricist Gene Lees.
