I've been trying to get into Rush for a while and I just got moving pictures. I like a few songs from the new album like Far Cry and A Larger Bowl. Is it the best old album to start with or should I get another one?
Moving Pictures is probably their top album, the band reduced the length of the songs but still kept their complex playing style and started to use synths as a ''real'' part of the compositions, they even incorporated some reggae elements in a song. The whole sound is more like new wave prog than classic prog though.
If you enjoyed MP then run and get Permanent Waves right now, both albums have similar musical patterns and aren't far between each other in terms of quality.
2112 is another classic by the band from their older era, full of hard-rocking riffs and a really heavenly acoustic guitar work, all the songs are awesome, especially the 1st one, which is enormous. The album is slightly psychedelic in parts and the vocal melodies are so passionate it's priceless.
The 3 albums above are probably the greatest but Fly by Night(basically Rush in a Zeppelin mode), Hemispheres(not too different from 2112), A Fareweel to Kings, and Signals are incredible too. As for the latter stuff, Counterparts is a quite good album from the 90's, full of well-written grungy(not grunge =p) tunes, Vapor Trails is decent, and i think that the new one is fucking great.
