Listening Post got the chance to hear those “vinyl on one side, CD on the other” CDs that are sure to increase CD sales by at least dozens of copies, and guess what: They don’t sound that bad! And really, the vinyl-CD twofer doesn’t sound that far-fetched as a gimmick when you compare it to the other “special CD” offerings available from Optimal Media Production, the German company that manufactures the dualdiscs:

Freestyle-Disc
A small trick with great effect! Due to a partial metallization of the disc, specially chosen images float through the room, appearing three-dimensional and extraordinarily vivid.
Many different styles are possible.

Perfume-Disc
The CD as a sensory experience!
The scent is integrated into the surface layer of the perfume-disc and released by light rubbing.

Why not combine the two? Just think: a disc full of “relaxing” music on a magic-eye disc that smells like essential oils–it gives you all the sensory experiences of going to a crummy mall, without actually leaving the house!
