I've recently bought quite a few klezmer CDs and many of them have similar selections of tunes, especially the classics from early USA recordings. There are slow melodies which are very beautiful I have some on the various CDs of Burning Bush- I can't remember which exactly, but there is a group of religious chants that they play as melodies, which are very moving. I asked a similar question a few weeks ago and got some useful info from american cats.
