Udora is a Brazilian rock band originally from Belo Horizonte, Minas Gerais, Brazil. Its members lived for five years in Los Angeles, California, United States, and moved back to Brazil in 2006.
The band was formed in 1997 by singer/guitarist Gustavo Drummond, drummer Jean Dolabella and bassist Ian Dolabella under the name Diesel and was one of the biggest names in the Belo Horizonte underground music scene. Shortly after guitarist Leo Marques joined and around 1999 Ian left the band for being contrary to the exposure they were having, being replaced by bassist Thiago Correa, nicknamed TC. In 2001, the band gained nationwide exposure after winning, through a battle of the bands-style contest, a spot on the main stage of the Rock in Rio 3 festival. They opened the last day of the festival, performing alongside bands like Deftones, Silverchair and the Red Hot Chili Peppers.
In August 2001, the band decided to move to Los Angeles in an attempt to break into the US market. The name Diesel was dropped to avoid conflict with Diesel jeans.
