Nava Tehillah (the Jewish Renewal congregation in Jerusalem led by Rabbi Ruth Gan Kagan) has released an entirely digital album of meditative High Holiday chants called Areshet.  You can download individual tracks or the entire album (and “name your own price”) from the site

Here is what they say about their latest release:

“This is a compilation our original chants for the High Holidays which we put together answering people’s request to have them available for use on their prayers this year. 2 of them are sketches taken from the half-baked process of our studio recording and most of them home recordings. They are offered free – and if you wish you can donate to support the completion of our recordings – by entering a sum of your choice. Chords and sheet music will be uploaded to our website soon.”
