Honestly, this is a better website than the official site. Somehow Marcos manages to have more up-to-date tour information than the official site. Also has more MP3s than Llan's site and lots of good links.
Multilingual site, very comprehensive, with everything you wanted to know about Asturain gaita (bagpipe) music. Even includes info on how to play, virtual sheet music, MIDI & MP3. A really awesome site!
