CA is my first RUSH album I have fully listened to. I haven't checked out their previous album although I have listened to their odd songs here and there (Tom Sawyer, and Spirit of Radio).
Since it release, I have listened Clockwork Angels for few times now (Thanks Spotify) and I have been really really impressed with the album. I cannot compare with their previous albums but all I can say is that I LIKE WHAT I HEARD! Great album.
It is very hot on my playlist and I listen at least once almost daily. So far, my favorites are the title track, Seven Cities of Gold, Halo Effect, The Anarchist, and The Wreckers.
The whole album is amazing.
CA is my first real commitment to RUSH and it has been great. I will be visiting their vast back catalogue in future.
