What's this Led Zep song?

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.

Kashmir ?

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.

Yep. Kashmir.

Quite possibly Rio, by Duran duran.

Dat be it! Thanks, all.
