Query: UFO's best studio album

While "Strangers in the Night" was a great showcase for how great the Schenker edition of this band could be, their studio albums were inconsistent and always included a couple of weak songs. Not so this one. This album has ferocious rockers, a good ballad or two, and finishes off with a great instrumental to cool you down. Michael Schenker is brilliant on this album, and the production is solid (also unlike most of their other albums). Get it... The closest thing to a must-have there is "Between the Walls", so you have to let how bad you need this be decided by how much you love UFO. A UFO fan should not be without this album.
