Therion is a Swedish symphonic metal band from Upplands Väsby. The band is initially focused on death metal before evolving into a symphonic style associated with more traditional heavy metal. The name of the group was inspired by the title of Celtic Frost's album "To Mega Therion" (1985) which in Greek (θηρίον) refers to the beast of the book of the apocalypse.
Since the release of the album Symphony Masses: Ho Drakon Ho Megas in 1993, the themes of Therion's albums have borrowed from different mythologies (Sumerian, Scandinavian ...) as well as a multitude of occult themes. If we except the group's first albums, very close to death metal, Therion gives pride of place to choirs and lyric singing as well as instruments such as violin or cello, unusual in the metal world. A symphony orchestra even participates in the recording of their albums Lemuria and Sirius B . The group members also quote Richard Wagner as the main source of inspiration: in the album Deggial is a metal version of O Fortuna, the opening song of Carl Orff's Carmina Burana , while the first CD of their album The Miskolc Experience (" Part 1 - Classical Adventures ") features great composers such as Antonín Dvořák, Giuseppe Verdi, Mozart and Camille Saint-Saëns. The band starts from death metal but under a different name: Demonoid.
Since 2006, Christofer Johnsson has decided to stop the growl - death voice - (at least for Therion). As a result, the voices of this type recorded on their album Gothic Kabbalah, released in January 2007, are the work of Mats Leven, Snowy Shaw and Katarina Lilja. On December 9, 2006, the band performed at the Bucharest Palace Hall in Romania for a show called "Therion Goes Classic" . He played with a symphony orchestra of 100 Romanian Radio Orchestra musicians, 70 choristers (Academic Radio Choir) and several guests. In 2007, opera singer Lori Lewis joined the band as guest. The same year, on the occasion of the International Opera Festival in Miskolc, Hungary ( Miskolci Nemzetközi Operafesztivál ), Therion played again with a orchestra and a huge choir. The concert was broken down into two parts. The first part was a rearranged version of some of the band's songs as well as some classic songs. The other part consisted of songs never played in concert. A DVD, The Miskolc Experience , came out as a result of this event.
