I think this is a great topic for a thread. For enjoying what we have in audio, stressing the outer limits is great. Are you accepting nominations or contributions for big bass? I don't have a spectrograph, or any ability to see ultraviolet either. But, here's a piece that I think is both fun and taps the bass pretty hard in a good way.\n\nBELLA FLECK FLIGHT OF THE COSMIC HIPPO\n\nIf you accept donations on this thread, I'd love to see what a spectrograph looks like.
