It's a good starting point for the FIRST of the Graveland eras, including the demos, "Carpathian Wolves" and "The Celtic Winter", which is basically really raw BM without many pagan/epic tendencies... "Thousand Swords" and "Following the Voice of Blood" were raw like the old stuff but took on a far more epic/pagan feeling. Then there was the more polished "Immortal Pride" type stuff, and now Darken has kind of gone in a really neat "mixture of Thousand Swords and Immortal Pride" type direction with the last few albums. So it is a good representative of the least interesting of all Graveland eras. To hear their best stuff, I'd suggest starting with maybe "Following the Voice of Blood" or "The Fire of Awakening".
