The boyband released 'Trust Me' earlier this month, serving as the lead single from their new album Rediscovered.
The collection will also feature promotional tracks 'Just Three Words' and 'Do I Need A Reason', when it's released on November 2.
Rediscovered will contain 12 new songs from the group, including 'Christopher Columbus', which helped inspire the record's title.
"For A1, this is the album that will bridge the gap between fans who've stayed true for all these years, to the people who are discovering them for the first time," their official website reads.
A1 now consists of Ben Adams, Mark Read and Christian Ingebrigtsen, after Paul Marazzi declined a reunion back in 2009.
