In the heady days of the post-grunge mid-'90s, it was hard to see who were real and who were pretenders -- and that didn't even take into account whose music would stand the test of time and whose wouldn't. If you look at their peers, you'll realize that not many were able to pull that trick off, and a collection like International Superhits! confirms that they not only were popular and good, but they could have held their own against their idols. Listening to this generous 21-track collection, it becomes clear that the group was as melodic as the Jam or the Buzzcocks and as impassioned as the Clash, only they were American and coming about 15 years too late. Distilled to their singles, Green Day sound fiercer than ever, and more musically vibrant -- and, if you're a fan of the albums, it's easy to realize that this just scratches the surface of what they've done. But that surface is spectacular -- proof positive that Green Day are one of the great punk bands, regardless of era. And there's no better proof of that than this addictive, essential collection.
