Query: Good, Not Their Best

While not up to the standards of Back In Black, Highway to Hell, and their debut, this is still a fine solid slab of hard rock from AC/DC. Everyone knows the title track is killer, but there are also other classics. "Big Balls" is great, always fun to hear. "Rocker" and "Problem Child" are two of the band's early classics. "Ain't No Fun" has some of Bon's best lyrics, and "Ride On" is the band's best heavy blues attempt. Pick this up after you get the classics.
