William Earl “Bootsy” Collins (born October 26, 1951) is an American bass guitarist and singer.

Rising to prominence with James Brown in the early 1970s, and later with Parliament-Funkadelic, Collins established himself as one of the leading names and innovators in funk with his driving basslines and humorous vocals. He later formed his own P-Funk side project known as Bootsy’s Rubber Band. He was a frequent collaborator with other musicians from a variety of genres, including dance music (Deee-Lite‘s “Groove Is in the Heart“), electronic big beat (Fatboy Slim‘s “Weapon of Choice“), and alternative metal (Praxis), among others. He is a member of the Rock and Roll Hall of Fame, inducted in 1997 with 15 other members of Parliament-Funkadelic. In 2020, Rolling Stone magazine ranked Collins number 4 in its list of the 50 greatest bassists of all time.

Collins was born in Cincinnati, Ohio, on October 26, 1951. He said that his mother nicknamed him “Bootsy”. “I asked her why,” he explained to a journalist, “and she just said, ‘Because you looked like a Bootsy.’ I left it at that.”

His brother Phelps “Catfish” Collins (1943–2010) was also a musician. He and Bootsy were once part of James Brown’s backing band, The Pacemakers.
