My two worst: 1) Oasis- their last US gig, ever (until the lucrative reunion tour...) George Mason University 2008. I waited years to see them and was so disappointed. Liam sounded awful, and spent the evening yelling at the sound board guy. The band looked totally uninterested. Opener Ryan Adams & The Cardinals blew them away. 2) The Black Crowes- Pittsburgh, 2006. Another band I waited forever to see. Like 15 years forever. Chris only sang about half the songs, and lots of their songs ended with minutes of feedback. I left the show early.
