Fijación Oral Vol. 1 (English: Oral Fixation Vol. 1) is the fourth studio album by Colombian singer-songwriter Shakira. It is also the first Spanish language album released by the multilingual songwriter since 1998. The album has won numerous awards worldwide, including five Latin Grammy Awards and a Grammy Award. This album and Oral Fixation Vol. 2 sold, combined, over 12 million copies worldwide and holds the record for highest debut ever for a full length Spanish language album in the United States.

Vol. 1 is the third official album, but first big name label release, by the rock band HURT, released on March 21, 2006. This album contains many tracks that are very dark in nature, and explain such suggestions as twisted logic from over-obsession in religion in "Rapture", pain from love in both "Falls Apart" and "Unkind", and drug addiction in "Overdose".

This album was released with two different packages. One was the standard jewel case, and the other a cardboard folding case, featuring a few more pieces of artwork inside, and a red bookmark attached to the case. Both pressings, however, contain exactly the same song material.

"House Carpenter" ends at 6:45 and the track continues with a rainstorm sound effect until 8:29, when an apparent hidden track begins. The hidden track is a guitar and several strings playing over the rainstorm, and continues for 1:04. The rainstorm is also heard at the beginning of this band's fourth full-length release, Vol. II. The song ends with the voice of a woman saying "I love you so much". The phrase is also heard in the background of "Unkind" at 1:24.

Alejandro Sanz (born Alejandro Sánchez Pizarro on December 18, 1968) is a Spanish singer-songwriter and musician. For his work, Sanz has won a total of fifteen Latin Grammy Awards and three Grammy Awards. He has won the Latin Grammy for Album of the Year three times, more than any other artist. Throughout his career, he has released a total of ten studio albums and six DVDs. The singer is noted for his flamenco-influenced ballads, but he has also experimented with rock, salsa, and hip hop.

Born in Madrid, Sanz began playing guitar at age seven, taking influence from his family's flamenco roots. He released his debut album at age sixteen, although he did not gain commercial success until his second release, Viviendo Deprisa. His next two records, Si Tú Me Miras and 3 also fared well commercially, but it was his 1997 breakthrough album Más that garnered international success. El Alma al Aire followed in 2000, selling more than a million copies in its first week.

In 2002, he became the first Spanish artist to record an MTV Unplugged album. His collaboration with Shakira on the single "La Tortura" reached number one on several charts worldwide. His albums No Es lo Mismo (2003) and El Tren de los Momentos (2006) showed Sanz experimenting with more diverse styles of music, while his most recent release, Paraíso Express (2009) served as a return to form for the musician. He signed to Universal Music Group in 2011 and is reported to be working on his tenth studio album.
