Basically, I do not represent the thesis that always used to positively everything should have been better and one can argue about taste. But in direct comparison to the albums Deep Purple in Rock, Machine Head and Co. arises for me happens to be the fact that this album has nothing to do with the content of genuine hard rock, but rather represents a solid and smooth pop / rock album , Of course, I expect the boys no other Deep Purple in Rock and see also one that every band has to adapt to the zeitgeist and changed accordingly. The band has to prove himself in the rock Olympus also nothing more. Only Deep Purple should reflect on themselves anyway, what they really are or at least were originally one, namely a real hard rock band. For that is what it has ultimately made large. In Purpendicular but I lack this impression and it's just too little ingenious moments available. When I listen to an album, you must listen to me immediately at the first give an Ah-Ha effect and that is not the case here with the best intentions. The so-called nice to hear (listen an album several times) brings because nothing. The music itself is not bad; but for Deep Purple definitely too little.
