Jim Nollman is a man who likes to hang out with animals and make music with them. He likes to sing and play instruments like guitars and drums, but he also likes to listen to the animals and make music with the sounds they make.
For example, he likes to play music with whales in the ocean. He uses a special device that lets him hear the sounds the whales make, and then he tries to make music that matches those sounds. He thinks it's fun to see if the whales will respond to his music.
He also likes to play music with cows. He goes out into fields where cows are grazing and plays his guitar or other instruments. The cows might moo or make other noises, and Nollman tries to make music that includes those sounds.
Some people think what Nollman does is really cool, because it helps them appreciate animals and see them in a different way. Others think it's silly, because animals might not really know what's going on or care about the music. But no matter what, Nollman enjoys spending time with animals and making music with them.
