His unique bass lines accent numerous commercials and are an integral part of today's music across many music viewing and listening fronts.

The 'Rock and Roll Hall Of Fame' yearly inducts the legends of Rock music. As of 2003, Chuck Rainey's bass lines and rhythm influence are the documented backbone of the original hit recordings of the following artist and the year they were inducted: Aretha Franklin (1987), Marvin Gaye (1988), The Jackson 5 (1997), The Rascals (2000), Steely Dan (2001).

Learning to play the guitar while on military active duty before college, eventually led him to professionally play the guitar with local bands in Youngstown and Cleveland after returning home from college and military obligations. Since his formal training did not encompass improvisational skills, his guitar playing ability was limited to 'rhythm playing.' He began to play the 'electric' bass instrument after it was obvious that his skills were more valuable playing single note patterns, which he displayed as a guitar player.

His arrival in New York City during the spring of 1962 coincided with the beginning of a new era in American commercial music. After a 3 and a half-year stint with legendary FT. Worth sax man King Curtis in New York, Chuck began an illustrious career as a 'sideman' in the recording studio along with Bernard Purdy, Eric Gale, Richard T., Donny Hathaway, Paul Griffen and Herb Lavelle to name a few.

Thanks in part to a brilliant conceptual nature of his musicianship, he made important contributions to the success of pop, rock, jazz fusion and rhythm & blues during the 60s', 70's and 80's. As the 21st century begins, Chuck Rainey is still very much in his conceptual playing ability and performance throughout the worlds music community.
