One European group has created a soundtrack to the "Batman" theme tune using the most natural of acoustic choices: the sounds of real bats.
Because the call of bats is well, squeaky and less pleasant for the human ear to take in, the group transposed recorded sounds down a few octaves. Then they assigned sounds to keys on a keyboard, they explain on their YouTube page.
A techno-flavored, but very convincing, rendition is the final product.
Have a listen below.
