Technically, I don’t know if this really qualifies at metal.  It’s more just standard fare mid-70’s American hard rock, simple and straightforward.  And very good for headbanging and air guitar.  You can probably skip over  50 seconds to avoid the unnecessary intro, which I refer to as the “sick pterodactyl” section of the song.  But once it gets past that, it puts the pedal to the metal (pardon the pun) and does not let up until the end.
