REBAELLIUN was founded in 1998 and is considered among the most important death metal bands to emerge from Brazil. Despite being formed more then twenty years ago, the band faced a considerable hiatus, which translates into less than a decade of actual activity and not more than three full-length albums under the belt. 

Until REBAELLIUN's dissolution (in 2002), the trio celebrated its most potent period, having released two studio albums, "Burn the Promised Land" (1999) and "Annihilation" (2001), via Hammerheart Records. They also played several tours - most of which took place in Europe - and shared the stage with Cannibal Corpse, Deicide, Vader and Behemoth. 

In 2015 the original line-up decided to reunite and release its third and last album, "The Hell's Decrees" (2016), followed by a European co-headlining tour with Pestilence, alongside shows at Party San Open Air and Brutal Assault Open Air. Unfortunately tragedy stroke shortly after, and took the life of guitarist Fabiano Penna in 2018. Amidst all the hardness, remaining members decided to keep the band alive. 

In 2020 REBAELLIUN is ripe for a new album, tentatively scheduled for autumn. The band is also gearing up to perform at Netherlands Deathfest and Into The Abyss Festival.
