Astral Weeks

So yeah, a couple of months ago I procured a copy of Van Morrison's 'Astral Weeks' album, and a copy of his 'Greatest Hits'. I have since come to the conclusion that Astral Weeks is complete and utter genius, and that it easily ranks in my top ten albums of all time.
What I wanted to know was this: Is anybody here familiar enough with the works of Van Morisson to suggest which album of his I should next invest in? I'm rather hoping that he has another album similar in style to Astral Weeks, and if you could direct me to that, then that would be just great. Alternatively if AW is a bit of a standout odd album and is something of a departure from his usual style, then which album would you regard as his 'best', and which would you recommend me to purchase instead?
Thanks in advance,
