MADONNA The Q Sound Experience (Rare 1990 Canadian promotional-only CD single, which served the dual purpose of introducing the world to Madonna's latest chart-smashing single, Vogue, and also of introducing the world to a new concept in music technology, 'Q Sound'. This particular copy comes complete with the Q Sound Technical Information Booklet, which is now difficult to find, and the CD itself includes both Vogue and Like a Virgin in their true Q Sound splendor!)
