A singer for me is more like someone who is standing alone with a microphone like Scott Walker, rather than someone who is bashing a plank and is spitting all over a microphone.
Playing and singing at the same time is pretty cool, but sometimes it's difficult to know when you can just really let go a bit because you've got to get back to bloody microphone and sing some stuff.
But live shows are cool. I just got back into the idea of enjoying it live.
