Miles was born in Newark, New Jersey and grew up in North Plainfield, New Jersey. He joined the musicians union at age nine in 1956 as a child prodigy drummer/pianist/vibist appearing with Miles Davis and John Coltrane among other talents of the day live and on TV shows including To Tell the Truth, Dick Van Dyke's variety show, and The Andy Williams Show. He made his solo artist debut recording at age fourteen in 1961, "Miles Of Genius", as drummer and composer with sidemen Al Hall and Duke Jordan. Miles continued to perform with his own band in the early 1960s in which he composed the material that enabled up and coming talents such as Woody Shaw, Eddie Gómez and Robin Kenyatta to display their talents. He wrote the instruction book, "Twelve Themes With Improvisations", published in 1963 by Belwin-Mills, and currently out of print. While a student at Princeton University, Miles concentrated his efforts on his piano playing, recording a live album in 1966 entitled Barry Miles Presents His Syncretic Compositions. He applied the philosophical term "syncretic" to music, defining the process of melding any combination of musical influences and styles together in the improvisational jazz idiom with originality. The combination of Miles's early jazz influences, his early Rock and roll background from the late 1950s and early 1960s, and his innovative "melting pot of musical styles" concept, resulted in this recording. Miles followed this release in 1969 with the eponymously titled album, Barry Miles, incorporating electric instruments including the electric piano. In 1971, Miles recruited his brother Terry Silverlight on drums along with guitarists Pat Martino and John Abercrombie to record his White Heat album which is regarded as one of the pioneering fusion jazz recordings. For the next decade, Miles recorded several albums in which he developed the principle of fusing styles together in jazz. In the late 1970s and throughout the 1980s, Miles embarked upon a prolific career as a keyboardist and Minimoog soloist on many recordings in the heyday of studio work, while working as Roberta Flack's musical director for a stint that lasted fifteen years. During that time, he composed, produced and recorded songs that Flack recorded in the film Bustin' Loose, and on her album Oasis. After Al Di Meola's stint as the guitarist in Miles's band on live performances and Miles's PBS special "Fusion Suite" in 1973, a long-lasting relationship developed between Miles and DiMeola that resulted in Miles's frequent appearances as keyboardist on DiMeola's albums along with co-production credits.
