Goes to "Jailhouse Rock" as covered by the Jeff Beck Group on 1969's Beck-Ola. With the ever talented (but for decades since, musically useless) Rod Stewart growling and howling his way through the lyrics, the song is transformed into something truly dangerous. Beck's guitar wails, screams and roars all over the mix, often in the background, but no less spectacular for it. The sound and playing are incredible and almost out of control. At times I'm convinced the whole track is going to simply explode, taking my speakers with it.
Elvis covers are a dime a dozen, but this is one of the few that stands out for originality, performance, and sheer wildness.
Best played with the volume at 11.
