Their albums The Divine Wings of Tragedy and V: The New Mythology Suite have given the band considerable attention within the progressive metal community. They also have achieved more commercial success with the 2007 album Paradise Lost; the band's 2011 album Iconoclast is the highest chart position and the most first-week sales in the band's history. Michael Romeo about the origin of their name: "So, you know, the music we were coming up with had the keyboard thing and the guitar, and some classical elements, so the word ‘Symphony’ came up and, so the dramatic thing, you know? So then, somebody said ‘Symphony X’ and we were like, ‘yeah, that’s cool’ it is that kinda thing, and the ‘X’ is the unknown and all the other stuff we do.
