While not providing full biographical descriptions, this finding aid to the Archive of Israeli Music at the Tel-Aviv University, David and Yolanda Katz Faculty of Arts, provides an excellent listing of Israeli musicians. It includes birth date and place of birth, major musical interests, a death date if any, when the person came to Israel, and a listing of major holding items in the archive. For an immediate, if modest, amount of biographical information for getting started with Israeli musicians, this listing is very helpful. The actual holdings in the Archive will, no doubt, reveal much more information about each composer and musician.
