BeatBox64 is a really fun map interested for anyone who enjoy music or just enjoy the sight of advanced redstone creations. When first entering the world you will be able to turn on an amazingly good beatboxing song which plays on repeat. But the best thing is that you can tune the song just the wayyou want it simply by toggling levers 512 differently tuned noteblocks.
