My friend and former neighbor Tim at our apartment building in L.A., Villa del Fuente, is really into the band Wilco, in fact he took Matt and I once to see them at The Greek. He has all sorts of really cool posters of the band up on his walls. In fact, I think the Oakland company The Small Stakes is responsible for half of Tim's decor. They have really poppy posters both in bold colors like the above Cat Power poster and neutrals for lots of independent bands. They add a little "edge" and "crispness" to a wall. I love them. Most posters are 18" x 24" and cost $25. If you really like one, go for it, they sell limited amounts so they sell out fast. Check them all out right here.
