Hoyt, thanks for answering.....your approach was exactly what I was going to suggest, so you saved me some typing. (Current CDs, then CoA, then the live CDs for an overview of their sound.)
Can't disagree with those saying Theli and Vovin are essentials, either. To this day, I instantly associate "To Mega Therion" -- probably their single best-recognized song -- with WREKage, the radio show I help host....'cause they were playing that song a lot on WREKage back when I first discovered the show, it helped hook me into the show and I never looked back. \m/
