Top Shelf Oldies is an nighttime-only Internet radio station dedicated to spinning the rarest of rarities from the ’50s and ’60s pop charts. (Actually, some of them are so rare that they never even made the pop charts.) In a single three- to four-hour shift, you’re likely to hear maybe two songs you’ve heard before—unless you’re an extremely knowledgeable oldies connoisseur.

Tuesday nights, Top Shelf Oldies offers a local connection with a show called “The Time Machine,” hosted by a rotating set of three men who call themselves the DC Dynamos. Tonight, and every third Tuesday night from 8 to 11 p.m., it’s Ken Carpenter‘s turn…although longtime D.C. residents and aficionados may know him better as Ken Sleeman, general manager in the ’70s for Georgetown University’s then-notorious WGTB-FM. Tune in for great oldies you’ve never heard, and drop into the chatroom to tell Ken hello.
