You will probably also love the Aeroplane Flies High boxset. A couple of its tracks appear on the Mellon Collie reissue boxset. They did a reissue of Aeroplane as well, taking Mellon Collie's 5 singles with a bunch of b-sides/covers they recorded during the Mellon Collie era to each CD. The boxset reissue adds even more material to each CD, instrumental demos, rehearsals, live performances. It's amazing the amount and quality of material from the Mellon Collie era. The extra Live From The Dark Globe collection is amazing. The set also includes a 30 minute live rendition of Sliverfuck.
I wish there were hi-res versions of the Aeroplane and Adore boxsets, like the other ones.
