a track called 'distance equals rate times time' from the pixies ............from the album 'trompe le monde' Fact: Although the Pixies' musical style has changed over time, the band is considered to be an alternative rock band alongside similar bands such as the Throwing Muses.[75] The Pixies explored a range of song styles in their songs—although many songs were characterized by Francis' distinctive yowling and lead vocals, with Deal's feathery backing vocals (on songs such as "I Bleed" and "Debaser") and Santiago's erratic lead guitar. The band's sound has progressed from an indie rock sound on Come On Pilgrim and Surfer Rosa, to a more sci-fi rock sound on Bossanova and Trompe le Monde. However, they have experimented with other genres of music, such as surf rock ("Cecilla Ann" on Bossanova), rock ("U-Mass") and pseudo-metal ("Planet of Sound" and "The Sad Punk", on Trompe le Monde).
