As a nice little treat, the folks at SuperGiant Games have posted a video of audio director Darren Korb and vocalist Ashley Barrett doing an impromptu performance of "Build that Wall," the track that won so many hearts (including mine) in the studio's lovely downloadable game Bastion.

In a nice bonus, Korb goes straight into "Mother, I'm Here," and finally the two perform the mash-up of the two songs titled "Setting Sail, Coming Home." If only narrator Logan Cunningham had moseyed in halfway through to provide some commentary.

"The Guitarist checked his tuning. Strings rang out, cold metal in the night."

Very cool, guys.
