I'm a one album fan of Vanden Plas so far. I love the album beyond daylight. It has strong melodic prog numbers like Nightwalker and Beyond Daylight. And good anthemic crunchers such as Phoenix and Free The Fire. I'm not too high on their ballads, though.
It's obvious these musicians are influenced by the musings of Dream Theater, yet differ sufficiently to keep things interesting.
I can't say I'm a fan of Christ 0, however. In fact, I've heard it nearly half a dozen times, and I fail to remember off the top of my head a single melodic line from it. Nothing. I know it's not bad, but it's hardly as memorable as Beyond Daylight. I also own Colour Temple, but find that album a little too timid in its approach to fully engage me.
