ENIGMAMCMXCa.D,” Charisma.The brainchild of German producer Michael Cretu, Enigma is an electronic potpourri ranging from Gregorian chants to streetwise hip hop. This interesting fusion has already Mt the charts with Sadeness, a tribute to the notorious Marquis de Sade.Unfortunately, when the novelty of Enigma's approach, wears off, the rhythms underneath it all have a sameness that’s irritating. The exception is “The Elvers of Belief,” the soulful piece that closes out the album.— Brian BourkeStaff Writer
