"Origins of Aggression" will be a very special double album to celebrate the band's founding and the 40th anniversary of Onslaught's debut album, "Power From Hell." "Origins of Aggression" will feature a total of 22 tracks in a double album format. Disc 1 contains re-recordings of the most important Onslaught tracks from the early years, while Disc 2 consists of punk and metal cover versions that made Onslaught the band they are today: songs jammed during rehearsals, songs that inspired the musicians to play an instrument. A fascinating musical journey through the band's genesis.
