I bought their latest record last night, The Acoustic Verses. All I can say is, WOW.
I have their other stuff, which is mostly prog metal/rock, they are always changing in some way. But this is the most drastic that I have heard. This album is completely acoustic with some string instruments added as well.
If you're into relaxing music, or acoustic music, or AWESOME music, I recommend this to you.
myspace.com/greencarnation has some samples.
Enjoy.
