That acoustic part is the intro for the song "In The Absence Of Grace", which appears on our most recent album "The Pale Haunt Departure".
We have quite a few songs that features clean singing vocals. I'm not sure what songs you have and haven't heard, but Paul doesn't do as much of the "spoken" clean vocals these days, he tends to actually sing more now. If you're looking for songs that prominently feature this, check out the songs "Autumn Reflection", "Through A Childs Eyes", "If Forever" and "Forever With Unopened Eye" for starters.
And just for the record, my opinion is that a good starting point cd for you to pick up by us is our most recent, "The Pale Haunt Departure". It's the most representative of where we're at and what we encompass musically. Thanks for the inquiries.
