I've heard this too, but I've been afraid to take the plunge.
Everytime I hear Papa Roach I think of "Last Resort" and I fucking hate that song and songs like it.
Maybe I need to check them out again though.
They did a complete 180 from that album. Their sound is a more rock/punk vibe to it. Jacoby sings more then anything and he completely dropped the rap-rock act. They actually started to slowly drop the rap act on the album after Infest. So it's been a generally progression, and they sound a hell of alot better. I know they have taken their licks from critics in the past, but they have really improved overall. I have a feeling that the general music public just remember Last Resort, Broken Home, etc., and that's a shame really. They have so much more to offer.
The first time I saw them live, Jacoby said a big influence of his was STP. They covered Sex Type Thing and fuckin NAILED IT. Besides totally making up for butchering Sweet Emotion, that moment made me realize that maybe this band has something. I am not saying they are the greatest band to come out of the early 00's or that. I am just saying that they were another victim of being generalized as a nu-metal/rap-rock band when they are clearly not.
