Three Days Grace

One-X is the second studio album by Canadian rock band Three Days Grace. This is their first album recorded as a four-piece band, as Barry Stock joined the group and took over lead guitar from lead singer Adam Gontier. The album was originally released on June 13, 2006. They worked with producer Howard Benson for the album, a decision which proved to be a great move for the band, as the album was both a critical and financial success
