At least it sounds like Robert Plant singing. It has a pretty heavy and insistent orchestral score behind it that sounds like something ominous: dadada…dadada…da da…dadada accompanied by a four beat/measure. It seems to me it was remixed as part of a more recent movie score, buy I can’t place it.
Most likely Kashmir, and the movie you’re thinking of was that Godzilla remake they did recently. Although I think that particular version used a Puffy-rapping-over-Kashmir abomination instead.
That’s definitely “Kashmir”, off Physical Graffiti.
Quite possibly Rio, by Duran duran.
Dat be it! Thanks, all.
