This week we conceptualise the concept album. Made popular in the days of prog excesses, concept albums have made a sort of mini comeback in recent years. Join us as Joe provides us one of his great big lists and we focus in on the best concept album of the 2000s. The Streets' sophomore album A Grand Don't Come for Free mixed Mike Skinner's idiosyncratic flow with everyday storytelling. It's a pretty great album and is done justice by a quiz based on the contested National Registry of Concept Albums.
