I was always a 2112 and Hemispheres guy.
R40 Live is just chock full of hits.

As for studio albums I can't stop listening to Moving Pictures (especially the B Side), Signals, Hemispheres, Power Windows, Presto, and Grace Under Pressure.

I listened to 2112 so many times. The only album of theirs that I don't get all that jazzed about is their first one. Everything else is 🔥
