Fantastic Four trailer removes any doubt that at least some of the soundtrack for the forthcoming film had to have been composed by Phillip Glass.

of course there might also be this bit of verification by way of The Guardian ...

Glass has done film scores before so it's not a surprise he's doing soundtrack work but it IS a bit surprising he's doing soundtrack work connected to a superhero film.  As composers labeled minimalists go Wenatchee The Hatchet has always preferred Steve Reich and Terry Riley and John Adams to Phillip Glass.

Apropos of composers ... today was, uh, Mozart's birthday.  Not actually a huge fan of Mozart (prefer Haydn and late Beethoven, for the most part) but, hey, might as well give a nod to Mozart's birthday having mentioned Phillip Glass, eh?
