THE most sonically dissappointing (lp) you own of great music?

The Who - pick any album. They basically all suck, although my reissue Quadrophenia LP is better sounding than most. Cheers,

I feel your pain. I have a UK "Quadrophenia" (Track) that sounds very good.

I sold my Classic "Who's Next" years ago, mainly because of the noisy pressing.

I have a UK  (Track) pressing of "Meaty Beaty Big & Bouncy" that sounds good on a (couple of tacks). Some are processed for stereo?

Given the 45 + years between, I stand firm on my initial post!

The Who BBC recordings CD is some nicely recorded live rock music recorded in an "intimate" setting featuring The Who in their prime.  Any Who fan needs this one.

Who's Next on Back to Black is not bad and of all the versions I have on vinyl, including a UK Track, this is the one that sounds accurate and has a full bass.

I agree with mapman! I recently picked one up at a yard sale, I was blown away with the quality. Inside the booklet revealed the secret, apparently King Biscuit recorded several live events using state of the art mobile studio gear, all I know is the quality jives with the explanation. I will be looking for more King Biscuit recordings!
