The album's sound was the result of the propulsive support provided by Hill and Beard, and Gibbons' "growling" guitar tone. Stephen Thomas Erlewine wrote that the album "brought ZZ Top their first Top Ten record, making them stars in the process". The album included the boogie-driven "La Grange" (written about the Chicken Ranch, a notorious brothel in La Grange, Texas, that also inspired the musical The Best Little Whorehouse in Texas).
