This new disc from the legendary 70s rockers probably wouldn't land under prog rock on its own strengths. Given the fact that a lot of their output is proggier than this, and that they were sort of proto-prog anyway, I'll nudge it far enough over to make that heading. This is cool hard rock with some songs that really shine brightly. Nothing here is weak, but some pieces eclipse others.
