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 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. It is their first and only album under
Sony BMG, the successor to
Sony Music Entertainment's original roots &
Bertelsmann Music Group. The Sony BMG joint venture was dropped in 2008, which led to
Bertelsmann's
Sony BMG stake going back to
Sony.
