Legacy of Grave Digger

Van Canto is a German a cappella metal band, founded in 2006 and composed of six singers and a drummer. While only two of the singers perform the lead vocals, the other four use their voices to imitate the guitars and the bass, with the help of amplifiers, in an attempt to sound closer to the original instruments. They use real drums in their music, instead of vocal percussion or beatboxing.

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.

Blind Guardian is a German power metal band formed in 1984 in Krefeld, West Germany. They are often credited as one of the seminal and most influential bands in the power metal and speed metal subgenres. Nine musicians have been part of the band's lineup throughout its history, which currently includes singer Hansi Kürsch, guitarists André Olbrich and Marcus Siepen, and, since 2005, drummer Frederik Ehmke.
