Early Life and Musical Roots
Paul Nelson Humphrey was born on October 12, 1935, in Detroit, Michigan, a city that would later become a cornerstone of American R&B and soul. Humphrey began drumming in his youth, inspired by jazz and swing music. After studying percussion formally, he joined the Navy, where he played in the military band.
Upon completing his service, he moved to Los Angeles, a hub for recording artists and session musicians. It didn’t take long for him to build a reputation as a reliable and stylistically flexible drummer, able to transition from jazz to funk to pop with ease.
Becoming a First-Call Session Drummer
By the 1960s, Humphrey was one of the most in-demand session drummers in California. His ability to play with both precision and feel made him a favorite among jazz musicians and recording artists alike. He recorded and performed with:
-
Les McCann
-
Wes Montgomery
-
Jimmy Smith
-
Kai Winding
-
Blue Mitchell
-
Gene Ammons
-
Charles Mingus
-
Lee Konitz
Humphrey’s work extended into rock, soul, and pop as well. He collaborated with Steely Dan, Frank Zappa, Dusty Springfield, Natalie Cole, and Jerry Garcia, among others.
Perhaps most notably, Humphrey played drums on Marvin Gaye’s iconic 1973 album Let’s Get It On, one of the most revered soul albums of all time. His subtle, sensual groove helped shape the intimate mood of the record.
Forming the Cool Aid Chemists

In 1971, Humphrey took a break from sideman work to form his own group, Paul Humphrey and the Cool Aid Chemists. The group was built around jazz-funk instrumentals that showcased Humphrey’s drumming style—tight, funky, and catchy.
Their debut single, “Cool Aid,” became a modest hit. Released on Lizard Records, the track reached:
-
#29 on the Billboard Hot 100
-
#14 on the Billboard R&B chart
The follow-up single, “Funky L.A.,” didn’t make the Hot 100 but did land at #45 on the R&B chart. The tracks were largely instrumental, blending organ grooves, brass accents, and clean funk rhythms. They offered a stripped-down, soulful sound that appealed to R&B audiences and found a place on radio station playlists.
These songs became collector favorites and received reissues on funk and rare groove compilations decades later.
Not Just a Bandleader
While leading the Cool Aid Chemists, Humphrey remained active as a studio musician and live performer. He was featured on The Lawrence Welk Show, a surprising turn for a funk-influenced drummer. But Humphrey’s adaptability allowed him to fit into many musical settings, from pop orchestras to jazz combos.
During this time, he was also recruited for work by record labels like Blue Note, Prestige, and Motown, contributing uncredited or lightly credited performances on countless recordings.

His ability to move between genres, maintain rhythm precision, and elevate a song without overpowering it, made him a go-to musician from the 1960s through the 1980s.
Later Years and Legacy
Though Paul Humphrey never achieved major stardom, he earned the deep respect of musicians and producers. His drumming has been sampled and revived in numerous compilations and remixes. In jazz circles, he’s regarded as one of the finest groove-oriented drummers of his time.
He continued performing into the 1990s and early 2000s before slowing down due to age-related health issues. He passed away on September 15, 2014, in Corona, California, at the age of 78.
His passing marked the end of a career that spanned more than five decades and quietly shaped the sound of multiple genres.
