First of all - in the interest of full disclosure - I am a Rush fan. There, I said it. I've seen them on every tour since 1982 at least once. I also play drums, and have off and on for many years.
The whole idea of a Rush cover band seemed almost absurd to me. You'll hear or see a song or two out on the Web and think "close, but no cigar". But I happened to see these guys open a local showing of the Rush documentary with about a half-dozen songs and my immediate reaction was "wow"!
Rush is no doubt a "musician's band", in that much of its audience play an instrument to some level of proficiency. With that in mind, I feel I need to add my $.02 in. When you go to the shows, you will not be hearing 3 guys trying to do a "note for note" duplication of every Rush song. Some other reviews on here might lead you to believe that is that case. It is not. But these guys have got it right. You can't replace the original. Thus the word "Tribute".
And what an amazing tribute it is! What makes these guys stand above their peers is not their musical prowess and love of Rush - it's that intangible "something". Like when you watch a stand-up impressionist do his rendition of someone famous. It's never exact, but there's something about the performance that makes you think: "yeah, he IS that guy!" It might just be Chris Nelson's truly stunning vocals. He's doesn't sound just like Ged, but at times, he IS Geddy.
And make no mistake - these guys can play. They have yet to do a song from Tom Sawyer to Cygnus X-1 where I've thought "oooh... so close". If they play it, they nail it. And they have a wonderful report with their audience. They come off being very down-to-earth and appreciative - not unlike Rush themselves.
These guys are coming into their prime in a very interesting time in Rush's career. One thing I can assure you - I have yet to talk to a Rush fan at one of their shows who wasn't "blown away". If that isn't reason enough to go see Lotus Land, then I don't know what is.
