The album, with a total duration of 54:43, included tracks such as Azul, the song that gives the work its title and which managed to position itself at the top of the Latin charts. Another notable piece is Lloviendo estrellas, which, along with Nuestro amor and Dos amantes, were part of a twelve-song tracklist. The effort behind Azul was recognized with a Grammy Award nomination for Best Latin Pop Album at the 44th Annual Grammy Awards, held in February 2002.
The production by Kike Santander for Cristian Castro on this album, Azul, was released under the BMG U.S. Latin label, consolidating the artist's presence in the musical landscape of the time.
