WOG was my second Tristania CD. I bought it soon after I got into BTV. At the time, I just started to appreciate BTV, so it didn't take much time for me to adjust to the WOG sound. I liked it immediately. Actually I think WOG was (and still is) the most accessible Tristania album, the growls were not as deadly as BTV or as aggressive/raw as Ashes, not to mention the music was more up beat, with large doses of choirs, female vocals and synths. For someone who used to listen to Within Temptation, Nightwish or other similar femme bands, WOG is probably the easiest album to convert them. I wish I had bought WOG before BTV since BTV took me forever to get into and the deadly growls had almost made me throw the CD away.
So..WOG had been my favourite CD for a while (in the beginning).
That said, now that I'm a devoted Tristania fan, I have come to realise that WOG is my least favourite Tristania album. Not to say I dislike it, I still love it very much and will always cherish it. But it seems to lack the magic WW, BTV and Ashes have. Songs on WW, BTV and Ashes (esp. Ashes) took longer for me to fully appreciate but they get better with each listen and each listen brings new sensations, no matter how many times I've heard them. (that's what Masterpieces are!) They just make me wanna close my eyes and enjoy, while WOG hardly has that effect on me anymore, saved for a few songs. Of course, Vibeke's vocals are as wonderful as ever.
