Yes, I was there... at least initially. I should preface it by sharing that I'm not a huge Beck fan but like his music and have for many years. I saw him a few years ago at the SC Civic and was very impressed. Very creative and artistic show.
My wife and I left this one after six, maybe seven songs. He didn't do anything wrong and he didn't sound bad, we were just bored. I'm sure it got much better and more interesting but we were unimpressed and only wondered, "How much better?" It was my birthday so we opted for Chinese foot massage instead. My cursory opinion was that he clearly thought that his music could withstand the rigors of an acoustic, stripped down platform, and for me, it didn't. He is so brilliant rhythmically (especially for a white guy from LA), and the absence of a live drummer and general effects were sorely missed from my POV. He did augment things with a drum machine but the kick drum sounded very muddy which unfortunately captured my attention. They likely corrected that eventually.
There was so much energy permeating the room 30 mins before scheduled showtime (8:00) which crested around 8:20 and trailed off by the time he actually hit the stage at 8:40. First few songs were uninspiring and flat which I thought surprised the audience, many of whom acquired tickets at a premium. Around song 4 or 5 he shared that he was going to do a couple of new songs. After the first one he said, "That was the first time I've ever played that song live," as I turned to my wife and smirked, "and hopefully the last."
I understand that my credibility is compromised because I left after 35 minutes but these were my general, honest thoughts. I'm definitely not a pessimistic artist basher, quite the contrary actually. I'm a live music junkie and have been for 30 years.
