Rift would be the album to do in my opinion. It has always been my favorite, and its really the only album with a story too it, so maybe they could throw in some commentary/other songs in between the album songs. I dont really care either way if they do it, bit if they did, id go nuts.
Ive always thought it would be interesting (i dont know if a band has ever done this) to play a show where everyone in the band (including the drummer) is facing directly away from the audience. It would make for a very interesting show where the crowd and the band would need to be totally focused on the music itself, rather than what the band/crowd is doing. Maybe its been done before, but i think it would be cool to see what would happen. Any thoughts?
