Smashing Pumpkins - One of the worst live bands I've ever seen. I gave them more than one chance, and they disappointed each time. Corgan couldn't be bothered to sing into the mic, and when he did it was gravelly, off key screeching. Every solo he took was just feedback and noise. The rest of the band phoned it in. And this was during their 90-91 peak. Soundgarden - Also 90-91. I felt like I was watching a sound check. Zero energy. Chris Cornell tried to pick a fight with someone in the audience. Ben Shepard threw his bass on the floor in disgust about 3/4 of the way through their set and stormed off the stage. Bad night, I guess. The other times I saw them they were incredible. More recently: Doobie Brothers - Not really a fan...but hey, y'know..."Classic Rawk!" Whatever. Their all direct-into-the-PA stage setup was just a wall of hiss. I've seen speed metal bands that weren't as loud. Chicago - They sounded like a cruise ship band covering Chicago.
