The Monster Tubulum
There's been a proliferation of pitched PVC xylophones in recent times, but a lot of them end up being somewhat cumbersome when it comes to actually get good sound quality. This guy has come up with the solution by making strange drum skins over the ends of the pipes. The result is a super cool sound coming out of a ridiculously cool-looking instrument.
Step aside massive pipe organs! You've found your match.
