The Black Keys is an American rock band formed in Akron, Ohio, in 2001. The group consists of vocalist/guitarist Dan Auerbach and drummer/producer Patrick Carney. The group began as an independent act founded after the duo dropped out of college, and they eventually emerged among a second wave of popular garage rock revival artists from the 2000s. Through October 2011, The Black Keys had sold over 2 million albums in the United States. Their debut album, The Big Come Up (2002), was recorded in Carney''s basement and forged their raw blues rock sound. Over the next decade, The Black Keys built an underground fanbase through near-constant touring of small venues, frequent album releases, and extensive licensing of their songs. In 2006, the band signed with Nonesuch Records and began to receive bookings for large music festivals. The duo released Attack & Release in 2008, their first album produced by Danger Mouse, a frequent collaborator of the band. Their commercial breakthrough came in 2010 with Brothers, which along with its popular single "Tighten Up", won three Grammy Awards. Their 2011 follow-up El Camino has received the strongest reviews of the band''s career and peaked at number two on the Billboard 200 chart.
