Talamasca (or Talamaska) is a psychedelic trance music project based in Paris, France. It is a project of Cédric Dassulle, also known as DJ Lestat. Dassulle played piano for over 13 years and started his career as DJ in 1992. In 1995/96 he was resident DJ at the Rex Club in Paris. He was influenced by trance music that he played during parties and wanted to create his own. In 1996 he met the other co-founders Steve Eli and Xavier de Galloy, house music producers with their own music studio. Together they decided to cooperate on a trance project and founded Talamasca. Dassulle currently operates it as a solo project.

Talamasca is also the name of a society of psychic detectives in the books of Anne Rice. His stage name is inspired by the Rice character Lestat. Dassulle has worked with other psytrance artists, including Nomad, Oforia, Space Cat, and Xerox. Talamasca also participated in founding the psytrance Label 3D Vision together with Christof Drouillet, DJ Mael and Javier Galloy. In 2004 Dassulle started his own label, Mind Control Records (also referencing Rice).
