Randy there's something about a fair haired lass that can play the violin and dance at the same time that just "trips my trigger". I have heard of Natalie McMaster but am not really familiar with her offerings. Very nice indeed. As far as Lindsey Stirling, I have one of her albums, "Warmer In The Winter (Delux Version)", and can readily recommend it to you. The delux version has 5 additional song on it than the regular album with the same name. Here is another Lindsey Stirling video that I really like . . . "Hallelujah". I think you would find this useful in your meditative exercise. By the way, "Hallelujah" is on her Warmer In The Winter delux version album.
Absolutely a perfect choice. You can see she is practicing Mindfulness to the music that is so important to her life.
Although I am an art historian by training listening to music is often a more powerful influence on me. My dad loved music and as a boy and teenager growing up in Connecticut in the 50s and 60s my parents attended a lot of musical theater. That is probably why my doctoral dissertation was on Rodgers and Hammerstein's Oklahoma! and South Pacific. It was somewhat autobiographical and half of it covered Cowboys & Westerns and the other WWII soldiers in the Pacific that were constant fare on TV during my youth. Ironically John Wayne played both types so he makes an appearance in it.
