Aussie Pink Floyd

Watching ‘Australian Pink Floyd Show’ on PBS… these guys are pretty good. Actually reproduce old PF stuff note, for note, stage shows light for light. When it first came on I wasn’t paying attention and thought "Holy Shit, Gilmour and Waters are on stage at the same time?"
Coming live to Seattle, 2 1/2 hr concert. Tempted to go and see if they do "echoes’ or “meddle”…

Are they like a cover band or tribute band or something?
