Guy Makes Guitar Out Of Concrete, But How Does It Sound?

I've been playing guitar for a loooooong time, and I've seen some really cool things done to them and with them. From Keith Urban's "Shattercaster" guitar that's covered in tiny little bits of mirror, to a plexiglass body guitar with LEDs buried inside, to an actual gold top Gold-Top Les Paul that cost more than most cars... But this is the first time I've ever seen someone create a guitar out of concrete! This guy got a DIY guitar kit and then proceeded to shape the entire Strat style body out of concrete. It's got to weigh a ton, and it took a lot of time to craft it, but how does it sound? Will this be the Rock guitar of the future (pun very much intended)? Check out the video below and see it from start to its glorious hardcore (see what I did there 😁) finish, including a sound check and playing demo!
