Stream of Passion is a progressive metal band with symphonic metal and gothic metal influences founded by Arjen Anthony Lucassen and Marcela Bovio. Because the musicians in the band lived thousands of miles apart, Lucassen composed the group's debut album, Embrace the Storm, over the Internet. It was released on October 24, 2005 through InsideOut Music.

With the exception of vocalist Marcela Bovio, who had appeared on Ayreon's album The Human Equation, Lucassen selected little-known musicians to form this band.

In August 2008, it was announced that Stream of Passion has signed to Napalm Records. They have since released their second studio album The Flame Within through Napalm Records. They have played some of the songs that are from the new album live.
