Joan Bakewell presents the last in a series of guides for record buyers. This week's contributors include critic Robert Cowan and saxophonist John Harle who compare notes on three recordings of Villa-Lobos's Bachiana Brasileira No 5 without knowing who the performers are.
Baritone Thomas Allen talks about the first records that were significant for him. And Petroc Trelawney makes a whistle-stop tour of recording formats past, present and future.
Producers Martin Cotton and Rosalind Furlong
