Amazing band right there. Not only do they have one of the best drummers around (amazing kit too) they gave an amazing guitarist and personally my favorite vocals. Their songs are almost like stories.
Rush have been around for quite a while, and since they only have 3 people, they all use synthesizers they control. Neil Peart along with being the drummer is the main lyricist of Rush. I think it's either you love his lyrics or you hate them. I personally think they're really cool. They write songs of the progressive genre.
Anyway I can't think of much else to write about them, bottom line is check them out immediately. Amazing stuff.
