This is a recurring theme with Ryan Adams.  He seems to have a very fragile EGO,and when the venue is not up to par (sound problems etc..) he has a hissy fit and takes it out on the very audience that makes his career (ie JOB) possible.   So, my opinion of his personality is that he is an immature asshole.  That being said, I do like his music.  Especially the stuff I have heard with the Cardinals.  His voice, songwriting and arrangements instantly remind me of Chris Hillman around the time he was with the Burrito Bros, and of course there are obvious nods to Gram Parsons as well.   Nice tunes.  Ryan needs to do what musicians are supposed to do, entertain his audience with the best music he can provide, and stop the narcissistic, self-indulgant adolescent diplays otherwise known as temper tantrums.  Very poor form.
