I think the band will be fine.
Everyone forgets how talented they are. When they are in the right place to write great music again, I have complete confidence they will.
This is a new outlook for me, but as a musician and songwriter, I am starting to understand where dave and the band is. They are just in a transitional period - adding influences and synthesizing new ideas. The fact that this CD is on hold is great news - they want to make something great and not rush things this time. Awesome.
I hope the idea of you doesn't even make the cut for the new album next year - how cool would that be? Not even put a tune like that on the album because they have so much other great material...
