Therion, 2 October 2024

Therion (formerly Blitzkrieg, Megatherion) is a Swedish symphonic metal band founded by Christofer Johnsson in 1988. Its name was inspired by the Celtic Frost album To Mega Therion. "To Mega Therion" is Greek for "The Great Beast" and was a title used by occultist Aleister Crowley. Originally a death metal band, Therion adjusted its musical style by adding orchestral elements, including choirs, classical musicians, and even a full orchestra at their concert performances. As a result, it has popularized the symphonic metal genre. In their biography, they state they have been cited as "the most adventurous metal band at present".
Therion takes its themes from different mythologies and practices, including occultism, magic and ancient traditions and writings. Thomas Karlsson, the head and founder of the magical order Dragon Rouge, has provided lyrics for the band since 1996.
