I went with ToT and 8vm.
ToT was the first album released after I had become a fan. I was still going through their back catalog and digesting everything, but ToT was just a fun ride. So I bounced back and forth between the "new release" and the rest of DT's music. I think when dissected with other albums that have more "depth", ToT doesn't hold up well, but it's the musical equivalent of a popcorn flick. As I Am remains one of their better singles, IMHO. Then with 8vm, it blew me away with the concept and the music (TALW and NE aside).
I feel ever release after I judged a little too harshly. Now fluent with every album, each new release I wanted to be the most amazing experience, rather than focusing in on how the release fits in with the previous discography as a whole.
