Recommend some Devin Townsend!

The new one (Addicted) is pretty good. I really liked Synchestra or Accelerated Evolution. Infinity had some really good tracks as well. Let's just face it. Anything that man does is "golden" to my ears. All SYL for that matter also.
 
I think that Accelerated Evolution and Addicted! are the easiest ones to get into. Maybe those would be great to start with. For me the Ocean Machine is the best. It will never leave my 512mb Creative Muvo mp3 player.. :)

From SYL I definitely prefer the City record. Awesome chaotic atmosphere in it.
 
Physicist has a few good tunes on it as well, and so does Ki....

I guess the bottom line is, get them all!
 
Listen to Ocean machine first, that was my first encounter with the god that is devin and it is still my favourite. Then check out Accelerated Evolution, and to see where he started experimenting with stuff check out Infinity its a great album to show you how some of the later albums got their influence.

also check out the song Deep Peace on "Terria" from 2:43 onwards is one of my favourite sections in a song ever.AMAZING

if you buy Accelerated Evolution get the version with the dvd. That will show you a good range of catalogue.
