I am so excited! There is an article about Yosef Karduner. I think he's one of Israel's best musician. My humble opinion LOLOL.
Here's the link.
OMG! One of my favorite songs that he sang was Shir La'maalot (Psalm 121). I tell you, everytime I listened to it, I would tell people around me, I'm sure he must have been davening (praying) just before he came up with that melody. Sure enough, in the interview that's pretty much what he says! He was meditating when this melody came to him.
