Perhaps it would've been more interesting to switch them around. What gave the third volume of the series (released last spring) a lot of its aesthetic tension was the fact the bands -- NOFX and Rancid -- spent their time covering each other's material. Here, the Bouncing Souls play only one Anti-Flag song and vice versa, though the Souls also cover Sticks and Stones and Cock Sparrer, while Anti-Flag takes on the Buzzcocks. It's less a friendly competition than a straightforward showcase. And "straightforward" is the watchword: only Anti-Flag leavens its trad buzzsaw attack (with hints of Jamaican skank). Both bands -- and especially Anti-Flag -- get by on enthusiasm, not to mention pungent songwriting: We can always use songs that ask, "National pride inside you/Building you up, or limiting you?"
