What are some interesting chord progressions for guitar?

C, Am, F, G is just so passe’ these days.

I’ve perused my guitar books, and pretty much every progression in them involves your typical C or G or F chord. I started a dreampop/lo-fi garage band not long ago, and as the guitarist and songwriter, I’m looking for interesting and “different” chord progressions to use in songs.

My parameters:

-They must be relatively easy to play. (for instance, Bflat diminshed isn’t easy to play)
-I’m not looking for harsh dissonance. Mild dissonance is ok.

Thanks, lovelies.
