Therion セリオンSymphonic metal band from Stockholm (Upplands Väsby), Sweden. Formed by Christofer Johnsson in 1987/1988. During the early years band's sound was very much death metal oriented, but rather soon developed into more complex and symphonic direction. For more than two decades now, Therion have been refining their superlative skills in combing metal with classic music elements. The band can easily master ripping metal riffs, epic operatic vibes, symphonic element and complex multi-layered choirs all within complex and flowing compositions.
