Where to Start?
I'm a great fan of Rush. I've been listening to them for the best part of 40 years and seen them 7 times in concert. Their most iconic album must be '2112'. This is very much a '70's concept album i.e. the whole album is written around a single theme.
Through the decades, their music has progressed from classic rock in the '70's, then adopting a more synth based sound through the '80's before returning to their classic rock roots in recent years.
Some of my favourites are -
Grace Under Pressure
Hold Your Fire
And I particularly like the more recent Clockwork Angels.
Any of their live albums are very good, with 'A Show of Hands' being largely recorded at the NEC Birmingham - I was there!
The odd album out is 'Feedback', in as much as non of the music is by Rush. It's all the songs that influenced them as teenagers, which they recorded in 2004 to mark their 30th aniversary. Well worth a listen.
