I've just finished reading "John Marsh. A Most Elegant & Beautiful Instrument. the Organ" by Martin Renshaw.
This deals with the life of John Marsh (1752-1828) majoring on his organ (and to an extent other musical interests). It's a fascinating and worthwhile read - how different was the world that Marsh lived in!
The book is available from "At the Sign of the Pipe" (http://www.signofthepipe.com/
