William “Billy Bass” Nelson, the original bassist for Funkadelic and a founding member of Parliament-Funkadelic, has passed away at 75. Born on January 28, 1951, Nelson died on January 31, 2026, just three days after celebrating his birthday.
News of Nelson’s passing was announced on the Facebook page of George Clinton, the founder and bandleader of Parliament-Funkadelic. No cause of death was given, though it was known he had been under hospice care. The confirmation came after an earlier mistaken report on January 26 that was later taken down.
Nelson began his musical path in Plainfield, New Jersey, where he worked at George Clinton’s barbershop during his teens. Clinton eventually invited him to join his doo-wop group, the Parliaments.
In 1967, the Parliaments released their hit single “(I Wanna) Testify”, which reached No. 20 on the pop charts and No. 3 on the R&B charts. The song established their commercial footing and set the stage for a more adventurous musical evolution.
Nelson played a key part in guiding the group’s next steps. He recommended bringing in guitarist Eddie Hazel, who would become a funk icon. Nelson also coined the term “Funkadelic,” a name that captured their emerging blend of psychedelic, rock-driven funk.
As George Clinton began redirecting his music due to legal and contractual complications, Funkadelic was formed. The band became known for its electrified, guitar-heavy funk that mixed rock, soul, and psychedelic influences. Nelson’s bass work was central to this shift, merging rock’s edge with funk’s groove.
Nelson’s bass playing became essential to Funkadelic’s earliest and most influential recordings. He appeared on their 1970 self-titled album, which marked the group’s bold experimental turn. That same year, he also played on “Free Your Mind and Your Ass Will Follow,” helping cement their reputation for pairing social commentary with sonic exploration.
His most celebrated contributions came with the 1971 album “Maggot Brain,” widely hailed as a landmark in funk music. Nelson also contributed to Parliament’s “Osmium,” further expanding the P-Funk musical universe. Beyond his bass work, Nelson was also a vocalist and co-writer on several of the group’s early recordings. He co-wrote and sang lead on “Super Stupid,” one of Maggot Brain’s standout tracks, and Clinton’s 2014 autobiography credits Nelson’s barbershop guitar strumming as the creative seed from which their breakthrough hit “(I Wanna) Testify” grew.
Nelson’s tenure with the original Funkadelic lineup was brief. He exited the group in 1971 after financial disputes with Clinton, an issue that would later affect other members as well. Despite the contentious split, his foundational work remained a core part of the group’s legacy.
Following his departure, Nelson pursued a diverse career as a session player and collaborator. He recorded with the Temptations, most notably playing bass on their 1975 hit “Shakey Ground,” the group’s last single to reach No. 1 on the R&B chart, bringing his unmistakable approach to Motown legends. He also worked with Lionel Richie, Smokey Robinson, and the Commodores, showing his ability to adapt while preserving his signature sound.
Nelson reunited with the Parliament-Funkadelic collective in 1994 and resumed performing and recording with various P-Funk offshoots. That same year, he released “Out of the Dark” under the name O.G. Funk, reflecting both his creative endurance and dedication to the funk legacy he helped create.
His musical achievements were formally honored in 1997 when he was inducted into the Rock and Roll Hall of Fame as part of Parliament-Funkadelic. He was one of 16 members recognized, celebrating both Clinton’s collective vision and the individual talents that powered it.
The Hall of Fame induction acknowledged Parliament-Funkadelic’s vast influence on modern music. Their fusion of funk, rock, soul, and psychedelia became a template for artists across genres, inspiring hip-hop producers who sampled their work as well as experimental rock groups.
Nelson’s bass performances became highly influential in hip-hop, with many of his early 1970s grooves heavily sampled. His deep, driving bass lines formed the backbone of numerous tracks decades later, reaching audiences who might not have heard the original Funkadelic recordings.
His influence was felt far beyond the funk world. Flea, the bassist for the Red Hot Chili Peppers, paid tribute after Nelson’s passing, calling him ‘the funkiest bass player that ever lived,’ adding: ‘Every note a mighty oak, a bull elephant, a bomb.’ His early Funkadelic recordings were sampled by hip-hop heavyweights including 2Pac, Snoop Dogg, and Dr. Dre, forming a musical thread that runs through the heart of the G-funk era.
Nelson’s legacy extends beyond his recordings. He contributed to shaping a musical philosophy that valued creativity, risk-taking, and teamwork over formula. That approach influenced funk, rock, hip-hop, and electronic music, leaving a lasting impact that continues to resonate with artists and audiences around the world.
