10 Most Underrated Aerosmith Songs

10. St. John - Permanent Vacation

Aerosmith don't really know much outside of down and dirty rock and roll. When they weren't trying (and failing) to make a pop crossover back in the late '90s, most of their previous output were them resting on their laurels while writing killer hooks for the masses. However, fans were in for a bit of a surprise when they threw on Permanent Vacation for the first time.

Right in the middle of the record, St. John shows these guys wearing their influences on their sleeve as a lowdown blues band. Long before the British Invasion sparked their minds back in the '60s, the real roots of rock came from the blues of acts like Muddy Waters, which this song is a clear descendent of. Instead of the rave up style boogie of the rest of their material, this song is about digging into a solid groove, with some of the most downplayed guitar performances Joe Perry has ever laid down.

It makes sense that these guys would eventually go out on tour with people like ZZ Top in their later years given how much old-school worship they bring to this one song. So next time that you throw on Permanent Vacation as your next party album, take a bit of a closer look to the backwater blues that you've skipped over so many times before.
