Perhaps the weather in the Philadelphia-Princeton area has been more conducive to film noir, but this week on “Picture Perfect,” I’ll be giving you the chance to dream about the great outdoors. Sundrenched plains and horses, that is.

We’ll combat the effects of light deprivation with an hour of music from some big movie westerns – including “The Big Country” (1958, with music by Jerome Moross), “The Big Sky” (1952, by Dimitri Tiomkin), “Big Jake” (1971, by Elmer Bernstein) and “Silverado” (1985, by Bruce Broughton).

It’s all BIG this week, under the bright, open skies of the American west, on “Picture Perfect,” music for the movies, this Friday evening at 6 EDT, with a repeat Saturday morning 6; or you can listen to it later as a webcast at wwfm.org.
