Definitely a quirky band.
If you want to hear how GREAT this band can be, listen to 'Sugar', 'Chop Suey' and 'Inner Vision'.
If you want to hear how CRAPPY they can be, listen to the songs they played last night on SNL.
They are a band that generally frustrates me. They can sound awesome on one song, then they can annoy the crap out of you the next. On some songs, the singer sounds great. On others, he ruins it all by himself.
Best example: Listen to the song 'War'. The band kicks your ass in that song. But the singer's lyrics are terrible. And there's this horrible interlude inbetween.
