The Annenberg Space for Photography has an INCREDIBLE exhibit on display right now til October 7th called Who Shot Rock and Roll? The exhibit features film photography of famous musicians, mostly from the 60's to present, and is FREE. If you go during the weekends, parking is $1. And it is right around the corner from the Apple Pan, which if you haven't been, it's an LA must-do.
I say this over and over again, but I'll say it again... If you live in LA, take advantage of your time here and do awesome LA things!! This is something you will definitely enjoy if you like music and you like photography or art. There's no photography allowed inside, but I did take some pictures of the surrounding buildings:
