"Uno" is the debut song by English rock band Muse. Written by lead guitarist and singer Matt Bellamy, it was released on 14 June 1999 as the band's lead single from their debut studio album Showbiz (1999). It reached number 73 on the UK Singles Chart. Background and composition The song originally featured on Muse's second EP Muscle Museum EP. During recording, the amp used for the guitar blew up. This also happened with other songs while recording Showbiz. Music videos Three music videos were produced for "Uno". The first was recorded on Tower Bridge and depicts the band members standing still amongst moving masses of people, with clips from a live soundcheck intercut. This video has been condemned by the band, who have described it as "shameful" and "embarrassing". The second video—directed by Wolf Gresens and Bernard Wedig—shows the band playing in a room while a woman navigates through a series of corridors in an attempt to find them. She reaches a door behind which Matthew Bellamy appears to stand, though upon opening it she finds a large pit, which she manages to avoid falling into. The video ends with the woman staring at a door numbered '1', which appears to be the same as the one she started at. The third promotional video for "Uno" is made up completely of live performances. Release "Uno" was issued on 7" vinyl (backed with "Agitated") and partially transparent CD (with the B-sides "Jimmy Kane" and "Forced In"). Also, an acoustic version of the song was released on standard 7" vinyl. Live Performances "Uno" was performed for the first time in 1999 and for the last time in 2015. A live version of "Uno" was released on CD2 of the "Sunburn" single and in the DVD Hullabaloo: Live at Le Zenith, Paris.
