Theme - collecting music and the idea of the cd

So I've been thinking constantly about working around my own and my family's music collections - these being my Dad's massive vinyl collection and my own 150 cds. It's struck me how treasured these collections have become, as my Dad's vinyl generation has died out, the CD is the next to become obsolete in the download age. It's on this theme that I can keep things personal, socially and economically relevant.
