Some questions:

1. A lot of us already have Tom Sawyer and Limelight...is it worth it to get masters?
2. How will they deal with YYZ not having vocals?

1. I'd say it's worth it. I think the covers are fine, honestly, but for a small price it'll be worth buying Rush masters. However, hopefully they will be charted a little differently (because the covers don't get written exactly the same).

2. I'm not concerned about this. No one's forcing anyone to buy it, so it really doesn't matter to me how it's done, as long as they don't do something stupid like try and add in singing. -_- My guess is the singer will just play tambourine through the whole song.

YYZ would be easy to 100% then. I might only get YYZ

Vital Signs will be awesome.

What if they make you sing the synth part? Ewwwwwwwwww....

It'll probably not let you play the song while a singer is present.

Definitely one of their best albums.

Red Barchetta! Bass will be awesome on that.

when does it go up?

I <3 Rush.

Really glad I didn't get Limelight, especially after seeing the master of Working Man . . . which was released after the cover was available. 

I mean, how pissed would you be if you had bought an underwhelming cover, only to see the master track available for download?  

And, about YYZ, I'm interested to see how it will play out.  A lot of my favorite music lacks lyrics, so if Harmonix can nail voiceless prog-rock, then we can move on from there.  Wonder if the guitar chart will be identical to the Guitar Hero II chart?

It's been confirmed on the official Rock Band forums that YYZ will not play with a singer. It will be grayed out in solo tour, and they simply will be excluded if a singer is present in the band.
