Guapa (English: Pretty) is the fourth studio album released on April 25, 2006, by Spanish Pop rock band La Oreja de Van Gogh. On December 5, 2006, Más Guapa (English: Prettier) was released exclusively in Spain and Mexico. Two months later, on February 13, 2007, the album was also released in Chile. Más Guapa includes a second disc of previously unreleased material from the Guapa sessions, as well as from recording sessions of previous albums. The album won a Latin Grammy Award for Best Pop Album By a Duo or Group. Guapa is the band's last album with Amaia Montero as lead singer. Recording The album's composition began in February 2005. By November of that year, there were already 18 tracks that would probably be in the final album. It was recorded in London, England in Abbey Road Studios from December second through 23rd, 2005. In January, 2006, they began re-recording in Madrid and reporters from TV channel Cuatro were present throughout to later publish a report regarding the album. In spite of the group's desire that a report not be made, a DVD was included in certain versions of Guapa. The album was produced with Nigel Walker. Its publication coincides with the 10th anniversary of the group's existence. Guapa contains thirteen songs that mix the band's typical pop with reggae, ranchera, a bit of bossa nova, some sounds from the 60's and 70's, a few techno arrangements and recollections of American music. In this CD the artistic maturity of the group becomes apparent in their lyrics as well as their melodies with songs like Noche (Night), Muñeca de trapo, (Rag Doll), and Perdida (Lost). It was the most anticipated album of 2006 in Spain. Originally, the release was set for March 28, 2006; however, technical problems with a machine in Du Manoir made the premiere be on April 25, 2006. When Muñeca de Trapo was released as a first single in Los 40, it was quite a success. Two days before its official premiere, the telephone company Movistar offered a Sony Ericson phone with the 13 tracks from the album and the video of the first single preloaded in the phone, causing the album to already be pirated before its official release. By December 2006, the album already had seven Platinum CDs. The album won the Latin Grammy of 2006 as best pop album by a group or duo.
