There are a couple of YouTube videos around if you want to see who I'm talking about, although last night's performance was like neither of them. In the first video below, he performs with a group of musicians while two dervishes turn, and in the second, he reads from Quarrelling with God before he plays.
He would introduce a poem and pass the book around for visitors to read, and then he would play a looooong song in a single rhythm, usually two or three mystical poems strung together.
Lucky us -- the DH and I have some of his music already. Last night, 'cause it's my birthday week, I bought the book and another CD, which I'm listening to now as I type this post.
You can hear from the YouTube video his rich baritone and excellent musicianship. What you can't get is the experience of a long, relaxing evening listening to intricately woven stories, and gentle laughter. Ahhh, a nice way to spend a cool, rainy spring (semi-birthday) evening with friends.
