I've had the wonderful fortune to visit various amazing places.  Sometimes I brought recording equipment and caught some sounds.  I have not published any of this material, yet.  Some made lush ambient backdrops for songs.  There are so many wonderful records of nature out there that capture a moment in time and in a place.  Whale and frog songs are music to my ears....

 One really cool thing I like to do is to sample a river in many places along it's course, then create a track that takes you for a ride down the stream, blending one sample into another to convey that flow and power.
