If you know how to handle torrent-files, there are 4 shows already on
www.dimeadozen.org. In lossless flac or MP3-format.
Register on dimeadozen.org (if the site says 'full' just wait a quarter of an hour and try again).
Download a torrent-client (U-torrent) and install it. Now log on on Dime and do a search for Fleetwood Mac shows appear (also older ones). Click on the one you want, a webpage will open.
On top of the page a link will appear. Click on it and your computer will open your just installed torrent-client.
Speed will depend on your connection as well as how many users share this content. So, leave your computer on to share it for others as well (torrents do download from the computers of several users). Do not worry, it's safe...none of your other data will be hacked.
After download is complete: download a flac-player or a converter to convert it to MP3, open the folder with the files and play it!
I download directly to my NAS en play the files thru my Sonos-system. Works perfectly.
Already available are:
Mohegan Sun, Columbus,
St Paul en MSG from different sources. The Mohegan Sun is imho the best soundquality so far!
