Rock and Roll and health care are rarely subjects one mentions in the same sentence, but Open Door Family Medical Centers in New York is thumbing its nose and convention and mixing it up. The largest federally qualified community health center in Westchester County has broken the mold for fundraisers in the past by producing bi-annual concerts that have played to sold-out audiences. This go around the B-52S are the headline act in a concert set for April 11 at the Performing Arts Center. The B-52s are the groundbreaking band that put Athens, Georgia on the musical map in the late ’70s with hits like the “Love Shack” and “Rock Lobster,” and conquered the world with its savvy hooks and unconventional approach to music-making. VIP Tickets are available online at www.opendoormedical.org. The fund-raising concert presents a rare chance to invest in good health care and a good cause, and also dance to some rockin’ good tunes.
