For anyone that doesn't get it and thinks we're insane, on artist direct's review of THP, they called Brad a "modern day guitar god" and that's a running joke here.
I read through this thread and here's my takeaway: Brad being unwilling to learn a song Mike wrote makes him seem like a huge asshole—being "lazy" isn't an excuse; both guitarists should learn each others parts. I understand not wanting to play particular songs live, based on their complexity or their emotional response on a personal (not fan-based) level if it's a song that means a lot to you personally and you don't want to play it live every night and end up cheapening the emotion you feel yourself...but not wanting to play a particular song live simply because you were unwilling to learn it is incredibly ridiculous to me, assuming it's true. Is it true? Meh.
