Formed in 1982, the Danish thrash metal band Artillery participated in the early development of the genre, and their highly energetic, riff-centric and often fast-paced music is similar in style to contemporaries such as Voivod and Megadeth. After releasing three full-length albums and touring extensively throughout the 1980s and early 1990s, Artillery disbanded in 1991, but reunited seven years later, only to disband once again in 2000 and reunite again in 2007; their discography now includes ten studio albums, the latest of which is 2021's X.
Agressiva 69 is Poland's most recognisable industrial rock band and a forerunner of the genre in the country. Founded in 1987 by Tomasz Grochola and Jacek Tokarczyk, the group has performed on the biggest stages in Poland and Europe with such stars as the Prodigy, Paradise Lost, New Model Army, The Mission, Front 242, Marc Almond and Alphaville; they have eight studio albums to their credit, the latest being 2012's Ummmet. Donuts Hole is a Catalan alt-metal quintet formed in 2009. Their music carries strong influences of metalcore—even veering into deathcore territory—and prog metal. They have released three LPs, the most recent being the 2020 concept album Fragmenta.
The remaining five bands—the finalists of Metal 2 the Masses—will be announced after the semi-finals.
