There are several groups or musical projects under the name "Sound". A number of the songs present in the charts are by "The Sound", a 1970s-80s English post-punk band, and this is an incorrect tag for this group. First usage of this name is credited to a duo of Eric Lumbleau (of Vas Deferens Organization) and Joel Zoch. They specialize in creating torrentially layered post-industrial, pan-ethnic psychedelic audio collages that resemble the avantgarde. They have released two albums, "Drunk On Sound" (1999), and "Screaming Zenith" (2002). Read more on Last.fm.
