Baroque, Classical and Romantic... the big categories of music history all have their big-name composers. But what about the composers less easy to categorise, the ones who fall in between the gaps? Tom Service goes in search of the Inbetweeners from all eras and, with the help of CPE Bach aficionado Andreas Staier, discovers how these once hugely influential figures still speak directly to us now.
