Chazzanim Avraham Baer z"l and Louis Lewandowski a"h created some of the most important books of chazzanut of the 19th century. בעל תפלה oder Der Praktische Vorbeter and Kol Rinnah U'Tefillah recorded for the first time, the oral traditions of the chazzanim of Western Europe. I have both, however my sight-reading is poor. Is there anyplace where I can find recordings of these nuschaot, in particular those of Baer, online?
I'm looking especially for niggunim for the Yomim Noraim (minchah, maariv, and Shabbat Shuvah).
