Not sure if the offer applies outside UK, but Vol1 and Vol2 of the above are available as MP3 downloads for £10 (normally £7.49 each)
Some items and composers I've not come across before, plus some I have heard of. Quite a few from "The Mulliner book", & "The Dancing Master", plus William Croft, William Walond, John Blow, Christopher Gibbons, William Boyce, Purcell, Giles Farnaby, John Blitheman (Te Deum), John Redford, Thomas Tallis, John Bull, Robert Johnson, Orlando Gibbons, William Byrd, John Stanley, John Nares, & Samuel Wesley. Also a number of A N Onymouse
Organist John Payne. I've not listened to all of it yet, but there is some great music there.
