Miles Davis was an American trumpeter, bandleader, and composer whose career spanned five decades and helped shape the course of jazz and twentieth-century music. Born in 1926 in Illinois and raised in East St. Louis, he began playing trumpet as a teenager and briefly studied at Juilliard before joining Charlie Parker's bebop group. Davis soon emerged as a major force, pivotal in styles from cool jazz with "Birth of the Cool" to hard bop and modal jazz, particularly through albums like "Kind of Blue" and "Milestones." Throughout the 1950s and 1960s, Davis assembled iconic groups with musicians such as John Coltrane and Herbie Hancock, constantly evolving his sound. His collaborations with arranger Gil Evans produced orchestral jazz classics like "Sketches of Spain." In the late 1960s and 1970s, Davis embraced electric instruments and new influences, pioneering jazz fusion with groundbreaking albums like "Bitches Brew." After a break due to health issues, he returned in the 1980s with a fresh sound, drawing from pop and funk and reaching new commercial heights. Davis continued performing and recording until his death in 1991. He is widely recognized as one of jazz’s most innovative and influential artists, leaving a legacy of constant reinvention and creative ambition.
