Correct, the vocals aren't horrid. The first half of the show is 'reasonable' but I think Meat gave it everything on Objects and just had nothing left in the tank. The venue doesn't help, what with it being a pokey theatre in the middle of nowhere, but I think the main problem is just that Meat looks really old and knackered throughout. The shows in the UK a few months later were much better and it's a shame one of those wasn't filmed instead.
I also agree that the In Search Of Paradise documentary does this show no favours either.
