Borealis is a Canadian power/progressive metal band from Orangeville, Ontario. Their music features soaring vocals, a focus on guitar riffs, as well as a bass-heavy backing rhythm. Their sound is likened to the more melodic realms of power metal, however, with each album they have introduced progressive elements to the mix. They are known for performing in an outstanding manner live; their first album was recorded in light of a well received opening performance for Sonata Arctica. In an interview, the band explained the origin of their name: "we were all hanging out one night and the northern lights could be seen above. We thought it would be a cool name, but with Aurora Borealis already being a successful band, we shortened it to Borealis".
When the band began in 2005, they originally employed a female opera style vocalist Siobhan O'Brian as their lead vocals frontrunner. In 2006 they recorded a demo Eyes of a Dream. Siobhan left the band between 2006-2007. Matt Marinelli became Vocalist in September 2007, and 2008 marked the year Borealis released their first full-length album, World of Silence.
