worst sounding great lps

Boss-born to run
Deep Purple-Machine Head
Meatloaf-bat out of hell
I was just listening to machine head. It ain't bad at all. Bat out of hell is two dimensional and lacking dynamics but ok otherwise.
Just about anything on Atlantic between 1971 - 1977. Especially Zep 4 and ELP Works Vol 1.
Utopia - Adventures in Utopia

Bright, thin and shrill but with great tunes. In fact, most things Rundgren mixed/mastered himself sound like crap.
agree with the rundgren comment, great music live, but the albums just dont come close to the experience
