The entire Fez soundtrack is sublime and amazing. To pick just one track from it to cover is a difficult choice. "Beacon" felt like something that would benefit from playing it live on acoustic instruments, but learning it from scratch was a decent challenge as my usual strategy of finding MIDIs or tabs of it failed. The time signature changes and slight tempo changes further convoluted the process. Disasterpeace is kind of a genius.
