"Sulam" is the Hebrew word for the ladder connecting heaven and earth that appeared to Jacob, the patriarch of Israel, in a dream. Rabbi Ashlag's magnum opus of Jewish mysticism is also called "Sulam", but the word also refers simply to a musical scale.
For the musicians around the clarinetist Moshe Berlin, giving this name to their band was a way of setting a program for their style of klezmer: combining dream and reality, heaven and earth, the hidden and the revealed.
The recordings for this CD stem from a concert in the Berlin House of the Cultures of the World in 1990 when the ensemble came to Germany for the first time.
