If you pass by Human Head Records and see the lights on at an hour when most retail operations would be closed, just knock. Chances are good that you'll be welcomed in for a hang and a dig, because this Bushwick, Brooklyn, shop literally takes no days off, holidays included. Given the sheer volume of quality, cross-genre used vinyl that passes through its doors, Human Head can’t really afford the down time. But it's also true that co-owners Travis Klein and Steve Smith just enjoy cultivating a clubhouse environment, where the musical discoveries and refreshments continually flow. It’s that vibe that initially attracted Shawn Dub and Phil Lembke – two regular customers and respected DJs around town who’d been hanging out at the shop so much that Klein wound up bringing them on as staff.
