Amen to that, Rev.

The Jimi Hendrix Experience 4 disk set
Phish, Hampton Comes Alive 6 disk set



those are the only two i have...

The Jacques Brel 10 cd Box Set. Contains everything he ever composed. Except for his film music.

These are really good if you like underground and obscure stuff from the 60's (although the Nuggets sets do have some hits on them).

Nuggets 4 disc set
Nuggets II 4 disc set
Rubble 10 disc set
Rubble II 10 disc set

The two Rubble collections are out of print as they where limited edition to begin with, but if you can track them down they are both well worth it.

Oooo that would be a damn good box set
