Finally found a video where you can clearly hear what spitting and drumming sounds like. Skip to 1:45 and you can really start hearing him. Thought I would share. Enjoy.
My hearing is pretty bad also due to too many years around loud machinery and listening to LOUD rock and roll music but I caught the spit and drum very clearly. Very good and yes, the gobble blows you away with the speakers up!! Enjoyed the video.
