As music goes cold and digital, an ever-growing contingent of music fans and artists is turning back to the snap-crackle-pop of vinyl. For those who continue buying actual physical music, the big surprises of an actual record far outweigh those of the disappointing CD. And of course, vinyl will likely always appeal to obsessive collectors. But most crate-diggers in town are reduced to doing so virtually or picking through mounds of holiday-music albums at thrift stores. This is no longer so if they head to Cutler Bay, miles from hipster central. In a strip mall next to a sports bar lies Musicians Discount Center, which, at first glance, looks like just what it is — a small, family-run musical instrument store that's a decent place to snag your first guitar. But head to the back of the main room. There the store sells crates upon crates of old vinyl collections. It's a curated one, though, and it's a digger's paradise, with records conveniently sorted by style but priced as though they were still languishing next to those holiday albums. The average price is $5. Gaze upon first pressings of New Order 12-inches from the '80s, paw through early hip-hop LPs by acts such as Kool & the Gang, or snap up rock classics by artists such as Chuck Berry and Santana. Just don't spread the word too much — oops.
