ZZ Top returned after an extended layoff in late 1979 with Degüello, their best album since 1973's Tres Hombres. During their time off, ZZ Top didn't change much -- hell, their sound never really changed during their entire career -- but it did harden, in a way. The grooves became harder, sleeker, and their off-kilter sensibility and humor began to dominate, as "Cheap Sunglasses" and "Fool for Your Stockings" illustrate. Ironically, this, their wildest album lyrically, doesn't have the unhinged rawness of their early blooze rockers, but the streamlined production makes it feel sleazier all the same, since its slickness lets the perversity slide forth. And, forget not, the trio is in fine shape here, knocking out a great set of rockers and sounding stylish all the time. Undoubtedly one of their strong suits.
