(2-CD set for the price of one CD) This item replaces WIND #5033 (which was originally released as a single CD) and has the same content as that item but adds a free bonus CD containing samples of animal sounds, including birds, frogs, monkeys and bugs. The original CD in this set features beautiful and soothing contemporary instrumental music interwoven with background sounds of the forest -- the listener hears the sounds of various animals subtly chirping and croaking along with the beat as piano, strings and percussion instruments play.
