The heavy metal band Sephion was founded by vocalist Brenno Fortress in Santos-SP. The first lineup, in December 2012, was composed by Brenno Fortress and Alex Steps. In January 2015, Stomp Gabriel Paiva, Pierre Setrak and Gabriel Santalla joined the band.
In six months of work, Sephion gained national recognition by winning the first edition of Imagine Brazil and they are already preparing for two major releases later in the second half of 2015: the video for the song "F*cking War" and the launch of an EP with six songs.

Sephion take their roots from heavy metal, with a significant influence of bands like Avenged Sevenfold, Pantera, Creek and Iron Maiden. The compositions are made in English and range from heavier arrangements until ballads, without losing the sonic identity of the band.
