Mono Records is on Colorado Ave in Glendale right by the 2 freeway, they moved last year from Glendale Ave. in Silver Lake. I love the store: prices are really cheap, there’s always a ton of stuff, with the caveat that condition can be spotty. There are two listening stations so you can audition before buying. Almost everying is under $10, and I’ve gotten some great bargains. The owner John was apparently a regular at Record Recycler in Torrence, a much larger version of the same kind of store. Definitely crate-digging places. Rockaway is a very different kind of store, lots of imports, most things in great condition, but it can be pricey. They do have a 10% off membership which costs $10 per year, I’ve made good use of that.
