At first glance, this is just a straightforward rock song, engagingly rowdy but familiar and predictable. It's solid stuff in this regard, but stick around past the 2-minute mark and it starts to surprise you.
There's this perfect, improv-y grind of a saxophone part that enters the mix and kicks the whole thing into a higher gear with outright distortion and blaring horn section before it spills into its unexpected last leg. This last leg for me is a stroke of genius: a skipping guitar remnant carries over to a sluggish beat with squawky horns, and we're suddenly propelled into outright beat poetry. Gotta love Cage the Elephant.
