As Neil Fallon describes on pro-rock.com :
“This song is one part cover song, one part original. Half of each verse is taken from Mississippi Fred McDowell’s “Fred’s Worried Life Blues.” The rest is our own concoction. When we wrote the upbeat part of the song, I couldn’t hear the typical blues sentiment. Instead, it kind of became a motivational speaker slapping himself out of a stupor. The chorus “Bang! Bang! Bang! Bang! Vamanos! Vamanos!” has nothing to do with guns. It got its start long ago when Tim, and I can’t recall why, said, “Vamanos! Bang! Bang!” Add a bit of John Lee Hooker and there you go. The ripping harp solo is none other that Five Horse Johnson”s Eric Oblander.”

On a July 2013 Episode of That Metal Show Neil describes how Lemmy Kilmister of Motorhead told him that this song was Clutch’s “Ace of Spades”.
