Radio DJs require extensive voice training, an encyclopedic knowledge of popular music, and the ability to contort their bodies to fit inside car dashboards. Share your appreciation for broadcasting wizardry with today’s Groupon: for $25, you get an annual membership to WTMD Listener Supported Radio (a $50 value).

WTMD constructs a sounding board for local artists and blasts the airwaves with a variety of engaging playlists. These public broadcasters secure annual funding for programming and events though private contributions and memberships. Annual members are secured with a complimentary new-music CD sampler, and can bask in the knowledge of continued community events, such as First Thursdays Concerts in the Park. These free music fests bathe historic West Mt. Vernon Park in the sights and sounds of homegrown musical maestros and sentient powdered wigs. In addition to live events, listeners can tune in to weekly programming mainstays such as Baltimore Unsigned, which exposes listeners to the quadrophonic delights of local talent. The boogie-inducing grooves of Dirty Soul Party incite hips to uncontrolled swivel fits, and Reggae Rhythms jams out island tunes for music-loving archipelagos. Memberships activated by June 27 will be entered in a sweepstakes to win a Cannondale Hooligan 3 Urban Solution bicycle, courtesy of Light Street Cycles, or a year's supply of coffee from Zeke's.
