I was today yrs old when i learned the name of this song! i can finally rename the file accordingly instead of just 'ACL Improv'

when i was at this gig i initially thought it was an improv. I loved it enough to snip it out of the audio file of the entire show that i have in my library to make it its own track. years later i heard it again when i was going through some random muse bootleg from a show years before ACL 2013 and im like it WASNT improv!!!! what is it?? well the other day someone linked to the riffs and jams page on musewiki and im like well it's in here somewhere and there it was!
