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

Madonna Bed Time Stories. Very very messy bass there. Extremely collectible vinyl tho.
"The Smiths" joins for poor mastering.

adding a CD:
  Agustin Barrios ‎– The Complete Guitar Recordings (1913-42)  3xCD box

These are remaster series from 78rpm records placed onto CD. The job was done sufficient enough to appreciate the great work of talented composer and maestro, but there are certainly limitation on clarity of these vintage recordings. All these distortions, imperfections, noise after all decay against an incredible spiritual performance of all pieces played.

Yea sell that bad sounding crap and never buy again.
I should probably sell my 3xCD copy I’ve mentioned of Augustin Barrios, but for some reason I don’t...

Most of Manhattan Transfer vinyls sound horrible, but CDs sound substantially better.
