Nora and Jay Ferguson of Sloan talk about how digital abundance in music has created a deeper thirst for the rare. In fact these days, it seems that rarity itself is becoming something scarce. Sloan has just released a new album called Double Cross, and the offering comes in a few different forms. There's your usual digital, vinyl, and cd. There are also limited edition, special Vinyl bundles that include exclusive offerings of one-of-a-kind album covers and band photos. The $99 limited edition sold out within 7 hours.

The demand is a reflection of something happening in the music industry right now. While digital files mean infinite copies, musicians are striving to create the rare collectible for their fans. A shorter version of this interview will air on the 149^th episode of Spark, but right now, here's Nora's full conversation with Jay Ferguson.
