Drawn together by a shared love of metal and prog rock, Riverside formed in Warsaw, Poland in 2001. The band intended to use their backgrounds in metal to explore new territory in prog rock along the lines of Dream Theater and Tool, creating spacious and experimental music with a metal edge. The band's full-length debut, 2003's Out of Myself, became a success, and prompted the release of Second Life Syndrome in 2005. In 2007, after a European tour in support of Dream Theater, the group released Rapid Eye Movement. In 2009 they put out another studio record, Anno Domini High Definition, which quickly became the best-selling record in Poland. ~ Gregory Heaney
