It includes Freddie Mercury's two official Queen-less albums, including BARCELONA, his jaw-droppingly bizarre collaboration with opera star Montserrat Caballe (who, besides Mercury, could ever have imagined such a pairing?), plus a bonus CD of singles and rarities. <p>The latter disc contains some of Mercury's best music. It includes a beautiful Phil Spector-ish version of "I Can Hear Music" (originally released, at the height of Gary Glitter's fame, under the parodic nom du disque Larry Lurex), and a wonderfully over the top remake of the Platters' "The Great Pretender."
