Mine include (besides all the ones on Stevecham's list!):
Wilco - Summerteeth
Foo Fighters - Colour and the Shape
Smashing Pumpkins - Melancholy and the Infinite Sadness
Jethro Tull's entire catalog (Steve, you forgot those!)
The Beatles albums, but this time the mono versions!
However, what I would like to see even more, would be some first issues on vinyl, (I.e. recordings only available on CD), such as:
Fiona Apple
Dave Matthew's Band
These two artist's music is just begging to be put on vinyl. (I do have the one DMB on vinyl, and it's awesome!)
