As far as I'm concerned, the best band in the world is Rush. I was first introduced to Rush by a friend who played me his brothers album: A Farewell To Kings.

I think it's fair to say it made an impression. :-) I bought the album and shortly after, bought tickets to see them in concert at the Glasgow Apollo. There are only three people in the band but when they play together, they sound like there's eighty-three of them! And this is not down to studio trickery - the three of them reproduce the sound live too. Individually they are stunningly good musicians but together they produce something greater than the sum of their parts.
A student asked me the other day what my favourite Rush album is. It was a question I could not answer. Obviously, I have a soft spot for A Farewell To Kings - the album that introduced me to Rush all those years ago but they are not a band who are content to just re-cycle the same sound over and over again. They grow and develop with every album and I like where they went next too with Signals
However, if you want a good introduction to Rush, you could do worse than their latest studio album: Snakes And Arrows.

There are some outstanding tracks on this album. Thirty-five years on and they are still doing new stuff - brilliant!
