I've really just been wondering how the heck some people are able to really rock out with their instrument and still play well. I dont mean mild movements; I can "dance" around with bass, no sweat; but I cant figure out how they actually swing their gear around and play well. I've also been wondering if there's any way to train to sing / talk while playing bass. As it is, I can't even answer peoples questions while Im playing bass, I just can't. Any advice? I've been jammig with a friend for a while, and we both have this problem, though me to a larger extent.
