Warehouse spaces in Williamsburg are rarely put to such noble use. Academy Records Annex is a staggering experience: droves of mainstream and rare vinyl, stuffed to the breaking point inside rickety crates. If you own a turntable and live within a 20-block radius, you probably visit this den more than the supermarket, but wax neophytes need not be afraid: The staff is knowledgeable and approachable, and the inventory is unbeatable (not to mention fairly priced). Peruse the stacks and use one of the store record players to test out your finds: Put in 10 minutes of searching, and you'll be astounded by what you discover. 96 North 6th Street, Brooklyn, 718-218-8200, academyannex.com (11211)
