"Permanent Waves" was Rush's foray into more concise composition -- the songs are shorter in length (except 'Natural Science', which is amazing nonetheless in its own right), more grounded lyrically, and just brilliantly delivered by all three members of the band. A very crisp and energenic work. As such, this may in fact be the most accessible album that Rush has delivered.If you're curious about Rush, this is probably one of the first discs you should pick up.
