HALLOWEEN is coming up – and nowadays it's celebrated with trick-or-treating, haunted houses and ghost stories are popular ways to celebrate. And in ancient times, the occasion was observed as the eve of the new year – a time when the worlds of the living and the dead overlapped. You’ll hear a sneaky, creepy concerto by Antonio Vivaldi, and an ICONIC piece of horror-movie music on a Halloween edition of Sunday Baroque, starting at 7 a.m. on WSHU-FM and our all-classical stream and at 10 a.m. on WSUF.
