Joseph Alberto Santiago is a Filipino-American guitarist and composer. Active since 1986, Santiago is best known as the co-founder and lead guitarist of the alternative rock band Pixies. After the band's breakup in 1993, Santiago produced musical scores for film and television documentaries, and he formed The Martinis with his ex-wife, Linda Mallari. He also contributed to albums by Charles Douglas and former Pixies band-mate Frank Black. Santiago resumed his role as the Pixies' lead guitarist when they reunited in 2004.

Doolittle is the second studio album by the American alternative rock band Pixies, released in April 1989 on 4AD records. Its idiosyncratic lyrics were written by the Pixies' main songwriter and lead vocalist Black Francis, and allude to surrealist imagery, biblical violence and descriptions of torture and death. Their 1988 album Surfer Rosa was highly acclaimed, leading to high expectations for its follow up. Doolittle was an instant critical success, and became their break-through album. It was especially well received in Europe, where the British music weeklies Melody Maker and Sounds both named it as their album of the year.
