amazingly great album. These guys are amazing they are the best punk band in the modern punk era. Well to be honest compared to most of the others they are the ONLY punk band to know. The album is a great punk opera but you can still tell its Green Day from listening to it even though it is different.
Gotta say that they are one of the best bands out there and have been from some time, they've totally blown away the rest of the punk bands now (ie avril lavigne, sum41, good charlotte etc) there is just a huge gap between Green Day and the others they are on their own level and nobody in punk comes close to them.
I'd also go out on a limb and bundle them together in the same category as the other greatest punk bands such as The Clash, The *** Pistols and The Ramones.
