Thickfreakness is the second studio album by American rock duo The Black Keys, released in 2003. The band's debut album The Big Come Up had been tremendously successful for an independent rock band and Thickfreakness further increased their profile. It continues The Black Keys' tradition of raw, heavy blues-influenced garage rock.
Songs such as "Set You Free" won the pair some mainstream success as being featured in the soundtrack of the 2003 film "School of Rock." Heavy comparisons to another American blues-influenced garage rock duo, The White Stripes, were often made by the music media.
