La Vela Puerca is a Uruguayan rock band formed in Montevideo, Uruguay in December 1995. Its founders and current members are Sebastian Teysera （lead vocals, frontman and main songwriter）， Nicolas Lieutier （bass guitar） and Santiago Butler （guitar）. The band's first appearance under the name La Vela Puerca was at a street party in Montevideo on December 24th, 1995. Since then several new members had joined. 　　In 1996, frontman Sebastian Teysera entered a demo tape in a band contest. The rest of the band wasn't aware of this until they found out they were listed among the twenty finalists. It was only a month later that they received a phone call informing them of their success. As a result, they were awarded 80 hours of free recording sessions. These sessions would turn out to be vital for the making of their debut album.
