1 is the second solo album by Symphony X guitarist Michael Romeo, released on 27 July 2018.

[1][2] It is his first solo album in over two decades (since 1994's The Dark Chapter) and his first release since 2015's Underworld with Symphony X.

[1][2] Most of it was created when Symphony X's vocalist Russell Allen was still recovering from the road accident he suffered one year before while on tour with Adrenaline Mob (in which his bandmate David Zablidowsky and tour manager Jane Train died[4][5]) and the other members were involved with other projects.

[6] Michael hired three musicians he's known for a while, including bassist John DeServio, with whom he went to high school.

[1][6] Two lyric videos, one for "Djinn" and another for "Fear the Unknown", were released on 29 June and 18 July, respectively.
