I feel this same way about Fall Out Boy. I call them "studio bands," and there's plenty of them around.
fall out boy sounds blah live. I think Blink sounds better live than FOB imo. But I agree, they definitely are a studio band, they make fun records for fun shows. But there is still a level of quality and skill expected by the millions of blink fans...
I can agree that FOB is also one of those bands, but I still think Patrick sounds better live than either Mark or Tom. That's not even close.
I will also say that when I saw Patrick a few weeks ago solo one of my first thoughts was "Holy shit he sounds so much better live solo than he did with Fall Out Boy." Part of the FOB live problem, in my opinion, is that Patrick's forced to play lead guitar half the time because Joe sucks and Pete's off doing flips, so the vocals suffer.
