Next time an old geezer tells you how great, epic, wonderful was the prog rock of the 70s, remind him of two songs which came about the same time: Zeppelin's "Trampled underfoot" and DP's "You can't do it right", which, unfortunately, happens to be in the album we are reviewing. Yeah, this is what all those old heroes of rock produced trying to jump into the disco craze bandwagon.If you haven't bought Stormbringer yet, pleeeeeease save yourself while you still have a chance.
