GRAHAM CENTRAL STATION (QUADIO) Quadraphonic sound, or 4. 0 surround sound, utilizes four audio channels connected to four speakers positioned at the corners of a listening space. The multi-tracked audio is mixed dimensional, immersing the listener in an expansive soundscape. Started by Larry Graham, bassist for Sly and the Family Stone, Graham Central Station released their Self-Titled debut in 1974. An exuberant hybrid of soul, funk, and pop, the album reached No. 20 on the Billboard Top Soul Albums, and their lead single, "Can You Handle It?" hit No. 9 on the Soul Singles.
