I wish to introduce you to Jordi Savall, one of the world’s most amazing early musicians.
Read on for more videos from this fantastic concert.
The concert is performed by one of his many groups called Hespèrion XXI. Before, he had Hespèrion XXI. He also has La Capella Reial de Catalunya (focused on 18th century music), Le Concert des Nations (generally Baroque with some classical), and a family group as well. This Wikipedia page helps navigate the map a little. I personally ignore the group names and enjoy the fantastic music.
You can by at least 64 [sic] of his CDs from Amazon.com!
