Do these guys have any good music?
A lot of 90s alt rock (nirvana, soundgarden, etc) and old school punk (clash, ramones). A lot of newer folky/indie stuff too these days too. I've always hated pop-punk, but I heard these guys were great in the 90s. Where do I start?
Insomniac and doomie are thier best.
American idiot was a well made record that was vastly improved on by bands such as Titus andronicus and fucked up.
For a mainstream band though, they're pretty good.
personally i think most of it is filler, but the tracks that aren't are genuinely pretty great Green Day songs.
Probably a couple more but those are ones that I enjoy thoroughly.
