Here are some of my favorite links with comments.
Lorie was the third "find" of mine through the PBS network. The first was about four years ago when I was in Chicago on a business trip. I was channel surfing in a hotel room and came across a PBS special about the music developed for the "Civil War" series: Jay Ungar, Molly Mason, and their group Fiddle Fever were playing "Ashokan Farewell" and I instantly loved the tune. You know that feeling when you hear a song for the first time and say "wow, this is neat", versus some other music that needs to grow on you for a while.
My next PBS music find was about two years ago when our local Tucson station played the St. Olaf's Christmas special. I tracked down the St. Olaf's bookstore through the Web and ordered my own copy of the special. It is a wonderful collection of Christmas songs.
