Two suggestions for ḥazanim (cantors) and shliḥei tzibur on the High Holidays.

In Uman, Ukraine (and in [the Breslov [community] in general) during the repetition of Rosh Hashanah Musaf, when when the ḥazan gets to the special brokha in the Amidah for Yamim Nora’im [the Days of Awe]:

Rabbi Seidenberg’s Prayer for the Earth is focused on global climate disruption (aka “global warming”), healing the skies, and the original blessing of creation. The liturgy is closely based upon the sun-blessing liturgy we used April 8th 2009. It is partly based on the Sefaradi liturgy for the Ushpizin on Sukkot, and on “Pri Ets Hadar” (The Fruit of the Majestic Tree) — the first ever Tu biShvat seder, included in the 17th century mystical work, Ḥemdat Yamim (ed. Rabeinu Yakov Ben Yom Tov Algazi). The prayer was first posted at neohasid.org, here. The prayer is based on the Pri Ets Hadar, Birkat Hachodesh, Sefaradi liturgy for Sukkot, and Malakhi 4, Genesis 9:14; Psalms 36, 78, 146; Deuteronomy 32:11, 11:12.
