A1 is an English-Norwegian pop group. Formed in 1998, they were originally made up of Christian Ingebrigtsen, Mark Read, Ben Adams and Paul Marazzi Their first single, "Be the First to Believe", entered the UK singles chart at #6 in mid-1999. They achieved success in the UK and other parts of the world in the late 1990s and early 2000s, particularly South East Asia & Japan. In the UK charts, they scored two No.1s and eight top 10 hits, 7 of which were written by the band. Adding to this, they also won a BRIT Award for "British Breakthrough Act" in 2001. They were managed by band manager Tim Byrne, who also formed Steps.
A1 member Marazzi left the band in 2002 citing personal reasons. The 3 remaining members subsequently decided to take a break in early 2003 due to exhaustion from being on the road for the best part of 5 years straight.
In December 2009, Ingebrigtsen, Read and Adams reformed A1, without Marazzi, for a series of concerts at the Christiania Theatre in Oslo. Since their comeback, they have released a number of new singles as well as their fourth and fifth studio albums, Waiting for Daylight, in 2010, and Rediscovered, in 2012.
