Donald Byrd set the standard for hard-bop trumpet in his days as a regular on the Prestige and Blue Note labels. His brassy tone and adventurous solos, coupled with a deep sense of the blues, made him one of the most in-demand trumpeters of the 1950s and '60s. Later, Byrd turned to the R&B-influenced side of jazz, which sustained him through several successful years in the late '60s. By the 1970s, Byrd had fully embraced funk and R&B in the form of his popular group, the Blackbyrds. In the '90s, Byrd was introduced to a new crowd when he was a featured performer on rapper Guru's groundbreaking JAZZMATAZZ.
