Sixty, which became a phenomenon in the United Kingdom after Root sent UK labels some of his demos. His single, "Just a Dream", hit the UK charts and resulted in A.M. Sixty doing a Peel Session. After touring stadiums in Europe and Japan, A.M. Sixty signed with V2 Records, releasing the album Big as the Sky in 2004.
