The problem isn't the vocals in the sense that Dave isn't singing all the words. It's the out of key singing he does as well as singing in a high register (which he can't) during parts that don't have high parts in the original songs. I love Van Halen...Eddie is why I play guitar and I own every CD, bootleg and all that jazz but I really don't think I'll be buying this after hearing it. Too much cringing and I don't want to remember them that way which is a shame because the music sounds great to me.
I'm with Frank, I love bootlegs, because I want the LIVE experience. I want to hear the mistakes, I want to hear the inane banter. I don't mind the flat singing or sing song style of delivery. I can't wait to see them this summer.
