British Pathé's VintageFashions channel is a go-to place for retro-fashion madness. Check out the incredible Umbrella Styles from the 1950s--every one of them--a must have!
The Temptations - I Wish It Would Rain. The perfect distillation of weather as mood.
Jimi Hendrix - Rainy Day, Dream Away/Still Raining, Still Dreaming, with UV meters for extra nostalgia. Rain as a metaphor for gettin' high and lettin' the world pass byyyyyy.
Why not watch "Singin' in the Rain"--one of the greatest musicals ever produced? Forget the nonexistent snow conditions in the Sierras for a couple of hours while you relive the dawn of the sound-movie era.
Beta Band - Dry The Rain. Dag gum it, Beta Band--we need the rain. But California's gone through this before. I once belonged to a pick-up baseball league and we played throughout five winters of continuous drought conditions before it finally rained for a month straight (like it's supposed to, around here). Thereafter, baseball became a spring sport once more. Eventually it will rain again and we will be all right. (As featured in "High Fidelity.")
