Peter Hurford, Romantic Organ Music Vol II (is superior to Vol I). The more common Vol I, is still good.
Peter Hurford, Hindemith Organ Sonatas, Argo 417 159-2 is excellent and worth seeking out.
Like most readers and posters here, I happen to enjoy Guillou, Murray, and Hurford. I have to buy them on web without auditioning first. I even doubt if their sonic benefits can be heard on the systems available in most CD stores. Please can someone who owns all their CDs, rank them in a purchase order for each artist.
