On the eve of the new millennium Radio 3 devoted its daytime schedule to an 18-hour-long broadcast surveying 2,000 years of western music, from an era before plainchant to today's computer-driven composition and music-making. In Cook's Tour, Christopher Cook revisits this acclaimed broadcast and presents his own highlights, as well as those requested by listeners. The result is a condensed version with a new twist, punctuated by news bulletins from bygone ages, and discussions and performances which free up the historical imagination to trace the musical connections between one generation and another.
