From what I understand, it was a very painful decision. I have faith in them. If they believed it was for the best, then so be it.
There are four people in the band now. As pathetic as it sounds, I hope they don't get another drummer. Let Frank play drums.
Bob Bryar is an amazing drummer, and an amazing person. He would give up everything for his passion. He even had wrist surgery for it. He could have never played drums if it went wrong, but he still took a chance.
I love him so very much and wish him the best of luck in what he pursues to do in the future.
Bob, you are a hero. My Chemical Romance will never be the same without your talent.
