Clarence Reid, the American R&B artists best known by his stage name Blowfly used when performing explicit raps, has died, his manager has said. He was 76. Manager and drummer Tom Bowker posted to Reid’s Facebook account, writing that “the genius known both by his given name and as Blowfly, the Master of Class, passed peacefully today.” The death was also confirmed by a Reid spokesperson, Rolling Stone magazine reported. On Tuesday, Bowker wrote that Reid had entered hospice care due to terminal liver cancer and multiple organ failure. Reid was a songwriter for Miami label TK Records, where he wrote soul and funk songs in the 1960s and ‘70s for big-name artists before coming up with his Blowfly character, Rolling Stone said.

Blowfly’s explicit lyrics spanned soul to hip-hop and he is considered “one of the earliest rappers,” the magazine said. His counterculture messages earned the artist, who performed in superhero-style outfits and masks, a strong niche following, although the nature of his lyrics kept him from mainstream appeal. In 1971, Blowfly released his first album “The Weird Wild World of Blowfly.” Subsequent albums included “Blowfly’s Party” in 1980, “Fahrenheit 69” and “Blowfly’s Punk Rock Party” in 2006. Big names from the music industry chimed in Sunday to wish Reid farewell, among them rapper Ice-T. “RIP and respect to the ORIGINAL. ‘Blowfly,’” Ice-T wrote on Twitter.

Red Hot Chili Peppers bassist Flea meanwhile wrote: “I had the great privilege of playing with BLOWFLY. So much joy. R.I.P. Clarence Reid.” But the world has not heard the last of Reid, who apparently had prepared a final album to be released posthumously.

“Blowfly has gifted us a final album, entitled ‘77 Rusty Trombones’ which comes out in February,” Bowker said on Facebook. “His sister Virginia and I thank you for all the love you have shown this week,” he wrote. “We also thank you for supporting Clarence’s 50+ year music career - especially these last few years.”
