On today's show, Vivian speaks with a variety of guests involved in the nightclubs of New York City - past and present - to explore the vibrant and thriving culture that exists after dark in the city that never sleeps. In the first hour of the show, she welcomes an absolute legend, the man responsible for introducing stereophonic high fidelity techniques into sound reproduction for club environments, forever changing the way club-goers _felt_ the music, Alex Rosner. Getting his start in the early 60s, Rosner designed and built the world's first cueing-capable mixer - named Rosie - and has masterminded the sound in countless iconic clubs including David Mancuso’s The Loft. Still operating his Rosner Custom Sounds Inc. (which he founded in 1967), he has designed and built more than 400 club sound systems, written numerous papers on the subject and has remained one of the most important minds working in sound today.
