There's just something about record stores in basements. Som Records is a prime example. This Logan Circle-area purveyor of vinyl specializes in rare jazz and soul LPs, with plenty of funk, disco, reggae, folk, blues, punk, and electronica thrown in for good measure. You'll also find a solid selection of Brazilian bands and hard-to-find rock albums, which are pretty impressive until you start browsing through their stock of vintage posters and show memorabilia.
