La Autoridad de la Sierra were born in 2004 of a small splinter group that left the duranguense front-runners K-Paz de la Sierra. Based in the duranguense hub of Chicago, the band recorded and released their debut record only a few months later in February of 2005. 100% Autoridad Duranguense hit the Billboard charts with force, landing close to the top of several Latin categories. In 2006, the band, only two years old, was honored with the Lo Nuestro Award for Group of the Year. La Autoridad de la Sierra have maintained their strong chart presence right through 2007's Momentos Inolvidables. ~ Evan C. Gutierrez
