I never acutally heard one Zwan song so I sure don't know what I'll be missing.
Most of the Pumkins albums passed my by, but I did see them on the Gish tour. They were totally unknown (well, to me anyway) and played on a monday night at a bar called Twisters in Richmond Va. Twisters had free shows every monday and we went for the free hang and cheap beer. Smashing Pumkins TOTALLY blew the roof off the place and the next day we all went and bought Gish, which in my opinion is a truly great record.
