There's nothing as good as the real thing, but it's nice to see people trying to keep their music alive after Peart passed. Rush certainly does deserve it. Even the Ohio St. Marching Band is covering their songs these days.
These guys get my vote. I've never heard anyone come close to singing like Geddy Lee and the woman is spot on with the most difficult of songs to sing in a "Passage to Bangkok." The guitarist is also excellent on a song not really meant for acoustic guitar at all. The bass player is into it, too.
