Frankmusik has given away so much great free stuff that it’s difficult to know exactly where to start. In many cases, it’s also better than his actual releases, so it’s definitely worth checking out.
A good place to start is freefrankmusik.com, which when I last looked was hosting his side project Vincent Did It‘s The SOPA Opera EP. If you can find their Long Live Frankmusik EPs anywhere, they’re very much worth tracking down.
Somewhere I’ve also turned up an excellent acoustic version that he recorded of Erasure‘s When I Start to (Break it All Down), which is possibly better than the album version, but I’ve no idea where I downloaded it from.
