Roots of Evergrey

Pain of Salvation is a Swedish progressive metal band led by Daniel Gildenlöw, who is the band's main songwriter, lyricist, guitarist, and vocalist. Pain of Salvation's sound is characterised by riff-oriented guitar work, a broad vocal range, oscillation between heavy and calm passages, complex vocal harmonies and the structures of their albums, syncopation, and polyrhythms. Thus far, every album released by the band has been a concept album. Lyrically, the band tends to address contemporary issues, such as sexuality, war, the environment, and the nature of God, humanity, and existence.

Therion is a Swedish symphonic metal band founded by Christofer Johnsson in 1987. Its name, meaning "Beast" in Greek, was inspired by the Celtic Frost album To Mega Therion. 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, they are considered pioneers of the symphonic metal genre.

Sabaton is a Swedish power metal band from Falun. The band was formed in 1999 by lead singer Joakim Brodén, bassist Pär Sundström, guitarists Oskar Montelius and Rikard Sundén, and drummer Richard Larsson, but has gone through multiple lineup changes with Brodén and Sundström remaining the only consistent members. The vast majority of their songs are about historical events, mainly wars and significant battles.
