Fantasy, September in the Rain), then Dexter Gordon on January 29, 1946 for the Savoy label (Long Tall Dexter, Dexter Rides Again, I Can't Escape From You, Dexter Digs In). The growth of bebop through 1945 is also documented in informal live recordings. Breakout By 1946 bebop was established as a broad-based movement among New York jazz musicians, including trumpeters Fats Navarro and Kenny Dorham, trombonists J. J. Johnson and Kai Winding, alto saxophonist Sonny Stitt, tenor saxophonist James Moody, baritone saxophonists Leo Parker and Serge Chaloff, vibraphonist Milt Jackson, pianists Erroll Garner and Al Haig, bassist Slam Stewart, and others who would contribute to what would become known as "modern jazz". The new music was gaining radio exposure with broadcasts such as those hosted by "Symphony Sid" Torin. Bebop was taking root in Los Angeles as well, among such modernists as trumpeters Howard McGhee and Art Farmer, alto players Sonny Criss and Frank Morgan, tenor players Teddy Edwards and Lucky Thompson, trombonist Melba Liston, pianists Dodo Marmarosa, Jimmy Bunn and Hampton Hawes, guitarist Barney Kessel, bassists Charles Mingus and Red Callender, and drummers Roy Porter and Connie Kay. Gillespie's "Rebop Six" (with Parker on alto, Lucky Thompson on tenor, Al Haig on piano, Milt Jackson on vibes, Ray Brown on bass, and Stan Levey on drums) started an engagement in Los Angeles in December 1945. Parker and Thompson remained in Los Angeles after the rest of the band left, performing and recording together for six months before Parker suffered an addiction-related breakdown in July. Parker was again active in Los Angeles in early 1947. Parker and Thompson's tenures in Los Angeles, the arrival of Dexter Gordon and Wardell Gray later in 1946, and the promotional efforts of Ross Russell, Norman Granz, and Gene Norman helped solidify the city's status as a center of the new music. Gillespie landed the first recording date with a major label for the new music, with the RCA Bluebird label recording Dizzy Gillespie And his Orchestra on February 22, 1946 (52nd Street Theme, A Night in Tunisia, Ol' Man Rebop, Anthropology). Later Afro-Cuban styled recordings for Bluebird in collaboration with Cuban rumberos Chano Pozo and Sabu Martinez, and arrangers Gil Fuller and George Russell (Manteca, Cubana Be, Cubana Bop, Guarache Guaro) would be among his most popular, giving rise to the Latin dance music craze of the late 1940s and early 1950s.
