While I was at ACL, I was disappointed in Neil Young a little bit. I love neil young, but he did not play any of is popular songs, which was sad because i was curious to see how his soft country songs would have been  fixed into a rock and roll sound. Another let down was M83. They did not really step up their game for what I saw. Music was to quite and they did not exite me. My favorite part of ACL was Weezer. They killed it. They perform with such accuracy sound almost exactly like in a studio.
