Moondog is a perfect compliment to the other Las Vegas record stores - some are all about new, trendy stuff, others are full of great $2-$10 used stuff - this one is about different stuff that you can't seem to find at any of the other shops. If you're into jam bands, punk or metal, go here first.
The owner is knowledgable and friendly to everyone. His prices are fair, but worth an extra couple bucks because you'd otherwise have to pay shipping to get your grubby hands on the stuff he's got.
