American cantorate presents all of the raw data of the 1984–86 NEH-funded project History of the American Cantorate, which was directed by Mark Slobin.
This free online resource includes over 100 listenable oral history interviews of cantors; a listenable 93-cantor core sample of sung selections of 8 liturgical texts, a first in Jewish music studies; questionnaire survey responses of hundreds of cantors and lay leaders; letters solicited from rabbis about working with cantors; research reports and data summaries commissioned for the project; and ongoing additions of archival documentation.
David Koussevitsky is one of the cantors featured in the study. A related video is here.
