I wonder if Dream Theater are one of those bands where you have to catch them on the right day? I've only seen them once and they were absolutely note-perfect, James' vocals included, but I have definitely seen videos of other performances where he's as flat as a fart or just out of tune completely.
Yeah, that's a fair point, I guess you can either throw yourself around the stage or you can actually play your surprisingly complicated music competently. Like I say, I had been at a punk thing during the day so I suppose I was still in 'enjoy poorly-played powerchords' mode! To balance things out, I did see Origin a couple of years previously and they absolutely blew my tits off - I'm not strictly a fan of technical DM but they were passing through my city and I was really impressed with the performance.
Godflesh are one of those bands I've been meaning to catch for years and have always missed through work or other tedious adult commitments. They definitely seem like a physical experience as well as a sonic one! It's wanky as hell to say (especially in a thread where we're suposed to be dunking on bands) but I love that about noise/extreme music performances - it's so fun to see how people move to stuff that either has weird rhythm or no perceptible rhythm at all.
