There are at least five artists named Uno: 1) Alter ego of german hip hop artist Twit One, used for the Instrumental Hip Hop Album "Testiculo y Uno - Hi-Hat Club Vol. 1" in collaboration with german producer Hulk Hodn as Testiculo. 2) Formed from the ashes of Osanna when the band split in 1974 by Elio D'Anna and Danilo Rustici along with drummer Enzo Vallicelli (from Hellza Poppin, who had played with Osage Tribe and Claudio Rocchi), Uno was a much-hyped band that went to England to record their first and only album with help from lyricist N.J.Sedwick and singer Liza Strike (of The dark side of the moon fame). The album is not far from late Osanna style (Landscape of life-era), with four English-sung tracks and three in Italian, with songs like I cani e la volpe in evidence, but didn't reach the success the band hoped. An English sung version of the album was released abroad, with a nice surreal cover designed by Hipgnosis (again a link with Pink Floyd), but didn't attract much interest. The three-piece band worked well in studio but couldn't get satisfying results when playing live, so the help from Danilo Rustici's brother Corrado (from Cervello) on guitar and bass was requested for live appearances. From this expanded line-up came the inspiration for a new band, called Nova. Enzo Vallicelli has kept playing (and still does it now, under his surname of Vince Vallicelli) as an appreciated blues drummer. 3) An alias of the japanese hardcore producer RoughSketch based out of Hokkaido, Japan. He mainly uses this alias on IOSYS releases. 4) Uno is a progressive rock/pop band from Kansas City. 5) Uno is a portuguese underground rapper.
