This is a video of musician Matthew Van Ness performing a 40 part multi-track orchestral cover of the Indiana Jones theme, playing all the different instruments with his voice. Does his voice sound like all those different instruments? Not particularly. Or generally, but you have to admire his dedication. If this had been my project I would have realized almost immediately that I could never be a piccolo, then pulled the plug and swung it around pretending it was a bullwhip.
