From Wikipedia: Quadraphonic sound uses four channels in which speakers are positioned at the four corners of the listening space, reproducing signals that are (wholly or in part) independent of each other. Quadraphonic audio was one of the earliest consumer offerings in surround sound.

If this sounds good to you, be sure to stop by the Harrison Center Friday December 7th. Michael Kaufmann AKA Future Rapper will be hosting the record release party for Asthmatic Kitty artist Chris Schlarb's 'Twilight & Ghost Stories'.

The record, which is officially released this Tuesday December 4th will be enjoyed in quadraphonic sound at the Harrison Center. The Harrison Center is located at 1505 N. Delaware. Be there by 7pm for all the fun!
