Stupeflip is a French music group known for its unique blend of hip-hop, rock, and electronic music, often described as experimental or alternative. Formed in 2000 by Julien Barthélémy (aka King Ju), the group is characterized by its eccentric style, surreal lyrics, and theatrical performances. Stupeflip has created a rich fictional universe around its music, including characters like Pop-Hip and the C.R.O.U., which adds a cult-like dimension to their work. Their sound is rebellious, humorous, and deliberately unpolished, gaining them a dedicated fanbase in the French underground scene.
