Don Tetto is a Latin alternative rock band from Columbia who made their commercial recording debut nationally in 2007 to great success before expanding their reach internationally the following year. Founded in 2003 in Bogotá, Colombia, the band is comprised of Diego Pulecio (rhythm guitar, vocals), Carlos Leongomez (lead guitar), Jaime Valderrama (bass, vocals), and Jaime Medina (drums). Shortly after forming, they began their rise to national fame on the rock radio station Radioactiva, which put in rotation a demo recording of their song "Pienso" in 2003. In subsequent years, the Bogotá-based radio station continued to support the band and put in rotation the follow-up singles "Yo Estaré Bien" and "Soledad." Meanwhile, the band worked on establishing itself as a powerful live act in concert, most importantly at the annual music festival Rock al Parque in Bogotá. Upon securing a commercial recording contract with the local independent label Cabeza de Ratón Music Entertainment, Don Tetto made their full-length debut in 2007 with Lo Que No Sabias. Recorded in collaboration with well-regarded Bogotá-based producer Jorge Holguín, Lo Que No Sabias included new versions of the band's previously released singles, spawned additional singles such as "Ha Vuelto a Suceder," and was repackaged with bonus material for international release by the American label 786 Music in 2008. ~ Jason Birchmeier
