Who's better - The Machine or the Australian Pink Floyd? I've seen the latter, not the former.
I've seen both, both Aussie only once and The Machine several times. The Aussies have a much more elaborate stage production, while The Machine's show is more stripped down. Muscially, I'd say it's a push depending on the night - both are pretty spot-on though. There's also a spin-off from the Aussie show called
Brit Floyd.. I saw them a few years ago when they were the touring Aussie show, but they spun off and now there are the Aussies and the Brits.
Really, you can't go wrong with any of them, and I'm sure there are other great ones out there, too.
