From what I've heard of these songs (I've tried to stay away) they sound much better than anything else post-reunion. Pumpkins have been my absolute favorite band for a while; needless to say I'm stoked about this.
When you listen to their new stuff, listen to "Song For A Son" first. It's laid out much like a 70's rock epic (a la Stairway To Heaven. Not saying it's a modern Stairway To Heaven, but it's got a similar format).
Saw SP live in December 2010. They put on a fantastic show. Really looking forward to this album.
