As somebody who plays the Viola da Gamba and is very involved in the repertoire, I am delighted to see there ae some people here who love this music. Lady Fitzgerald mentioned the Baryton - and I have a friend near me here in New York who owns two of them and often plays them professionally in concerts.
Earlier this week I attended a three-hour workshop for viols where we played some madrigals by Gesualdo.
Recently, I discovered an internet radio station which streams what is commonly referred to as "Early Music" and might be a source of interest to others.
It will give you the option to choose your method of streaming - WMP, iTunes, etc - which will open in a separate window so you can continue your other PC activities. The main window also has a "Playlist" option, which open a small window, providing information on the piece being played, as well as the performers - in case you want to find more by that particular composer or group.
It's completely free - although there is a "Donate" link on the main page - however they never interrupt the music to ask for donations.
