Musicians jamming out on electric guitars and drum sets usually come to mind when we think about rock bands, but this guy had a much different idea when he started working on his own.
Artist Neil Mendoza has built a seriously unique machine that creates beautiful music akin to the kind that music boxes produce -- but the melodies it plays are way cooler because they're made by rocks!
Controlled by a computer, "the rock band is composed of electromechanical instruments that make music with rocks by throwing them through the air, slapping them and making them vibrate," Mendoza said. While he does a great job of explaining how the machine works, it's really something you need to see for yourself.
