Peter Anthony Smith is an Australian musician. In his spare time he messes around with an EWI, an Electronic Wind Instrument, and records some terrifyingly accurate (and gorgeous) video game covers.
The above recording might be my personal favourite, the underwater theme from Super Mario Bros. but every single one of these covers has their charms.
Like this one from The Legend of Zelda: A Link to the Past.
Peter primarily records Nintendo music, but frequently takes it in different directions. Here's the special stage music from Sonic the Hedgehog...
All of his work is pretty spectacular. You can check out his YouTube page here
