Garry Marshall Shider was an American musician and guitarist. He was musical director of the P-Funk All-Stars for much of their history. He was inducted into the Rock and Roll Hall of Fame in 1997, with fifteen other members of Parliament-Funkadelic.

Parliament-Funkadelic is an American music collective of rotating musicians headed by George Clinton, primarily consisting of the funk bands Parliament and Funkadelic, both active since the 1960s. Their eclectic style has drawn on psychedelia, outlandish fashion, and surreal humor. They released albums such as Maggot Brain (1971), Mothership Connection (1975), and One Nation Under a Groove (1978) to critical praise, and scored charting hits with singles such as "Tear the Roof Off the Sucker" (1975) and "Flash Light" (1978). Overall, the collective achieved thirteen top ten hits in the American R&B music charts between 1967 and 1983, including six number one hits. Their work would have an influential effect on subsequent funk, post-punk, hip-hop, and techno artists of the 1980s and 1990s, while their collective mythology would help pioneer Afrofuturism.
