One big difference between this year and 1992, when Hurricane Andrew struck, is the fact that 25 years ago South Florida had a classical music station. Its music was a balm to many people; the Kings Singers’ You Are the New Day, played in the immediate aftermath of the disaster, has been cited as an inspiration for the region’s recovery. Now it’s the jazz station WDNA’s moment to step up to the plate. Perhaps, when this is all over, with Joao Gilberto’s Desafinado.
