I read "Your Band Sucks," so I'll have lots of ammunition here.
From SA:
I’m sure a lot of people have deduced by this point that a lot of what I say in these articles is nothing more than good-natured ribbing, and that I can’t really detest all of these bands as much as I claim to. Well, let me get one thing straight. I really, truly, and deeply in my soul loathe Pink Floyd. Their mind-bogglingly pretentious musical wankery makes Radiohead look like Smash Mouth. They engaged in, or in many cases were responsible for, just about every reprehensible, over-serious prog-rock abomination that you could possibly think of; they’ve got the double-gatefold concept albums, they’ve got the expensively animated album-film, they’ve got the children singing the lyrics, and they’ve got the notoriously high-concept concerts where workmen build a wall in front of the band as they play and shit like that. Rick Wakeman’s “Camelot on Ice” disaster, frankly, seems rather cute when compared to the kind of crap that Pink Floyd likes to pull. The music behind all these nauseating concepts is densely layered pop music for below-average high-school misfits who mistake spooky sound effects for creativity. Many teenagers go through a Pink Floyd phase in high school; if you were or are one of them, I’d seriously advise you to cut your losses and give away all your Pink Floyd records now, lest you become one of the creepy stoned burnouts who spend their lives wearing faded Floyd t-shirts like reeking albatrosses, forever unable to find gainful employment anywhere but a head shop.

And for Led, Dr. Thorpe says:
Way back in the days when music critics listened to albums with the none-too-generous expectation that they wouldn’t be completely fucking terrible, Led Zeppelin got mostly unfavorable reviews. However, sometime in the eighties, when the rock and roll well had almost entirely dried up, Led Zeppelin’s critical reputation was somehow transformed; critics went back and re-discovered them, realizing that while they were objectively terrible, they sucked about ten percent less than the new stuff that was coming out. Through clever historical revision, Led Zeppelin has gone from a band loved by audiences but hated by critics (like Aerosmith or Creed) to a band that was totally great and ahead of their time. They innovatively combined the British blues-rock tradition of totally sucking with the heavy metal tradition of writing songs about fantasy novels. Genius!
