Ben released the track himself on Twitter. i feel like "surfaced" fits more with a song being "leaked" or some really old b-side that gets around the internet after some friend of the band shared it.
but whatever, i'm just being picky. and the song is awesome.
I originally submitted that Folds posted in on his Facebook page. I found out through his twitter as well, but didn't feel like digging for the link. The "news" was altered to omit the Facebook reference. I don't care either way, but since you were wondering...
Anyway, I love the urgency in his piano work on this track. Definitely excited about this album.
