Formal recording of bebop was first performed for small specialty labels, who were less concerned with mass-market appeal than the major labels, in 1944. On February 16, 1944, Coleman Hawkins led a session including Dizzy Gillespie and Don Byas, with a rhythm section consisting of Clyde Hart (piano), Oscar Pettiford (bass) and Max Roach (drums) that recorded "Woody'n You" (Apollo 751), the first formal recording of bebop. Charlie Parker and Clyde Hart were recorded in a quintet led by guitarist Tiny Grimes for the Savoy label on September 15, 1944 ("Tiny's Tempo, I'll Always Love You Just the Same, Romance Without Finance, Red Cross"). Hawkins led another bebop-influenced recording session on October 19, 1944, this time with Thelonious Monk on piano, Edward Robinson on bass, and Denzil Best on drums ("On the Bean, Recollections, Flyin' Hawk, Driftin' on a Reed"; reissue, Prestige PRCD-24124-2).
