Before "Machine Head" or "Burn," in 1970, there was "In Rock." It was a very good year for Deep Purple apparently, at least musically. This album is surprisingly not one they are more commonly known for, or so i've noticed. If you like Rock n' Roll and you want your mind to be blown so far up your ass it hurts so good... than download this masterpiece. I can not begin to do this album justice by saying that it is probably one of the most brilliant rock album of its time and i don't know who would argue. BOW TO DEEP PURPLE YOU INSIGNIFICANT PIGS!
