I am not sure if anyone said this yet, but the piano is not the same as the one in ATM. The main difference is the lid. It is square, not very common on baby grands... This must have been a crappy piano, or not even a piano. Just parts made to look like a piano.... The piano looked, when it blew up that it was fake, with out a soundboard, and strings.... almost as if it was filled with loose dry dirt... I am not sure, but it is a guess, I have see a piano explode, and you see a little more snap... IDK, I am not a professional at piano explosions or anything.. Just an idea..
peace
