Classes on the Torah of the Alshich HaKadosh — Rabbi Moshe Alshich, the great sixteenth-century preacher of Tzfat — gathered by the Alshich (Alshech) Foundation, which also cares for his historic synagogue in the Old City.
The library is organized by book of the Torah and by speaker, and you can listen online from anywhere:

Rabbi Shmuel Schwarz (Manchester) — weekly parsha series on TorahAnytime, in English
Rabbi Eli Mansour (Brooklyn) — short Alshich HaKadosh classes on the weekly parsha
Rabbi Shmuel Wagshal — the “Sparks of Alshich” series on every parsha
Rabbi Shraga Rosenbaum — the Alshich on Eichah and Megillat Ruth, in Yiddish
Rabbi Yacov Mordechai Brandwyne and Rabbi Chaim Shmuel Geshtettner — classes in Sefer HaAlshich
Rav Aaron Lopiansky — the life, era and legacy of the Alshich

When you’re in Tzfat, visit the Alshich Synagogue on Alsheich Lane in the Old City, where he taught.
