20 minutes of droning, trance-inducing guitar distortion should put you in the Rosh HaShanah spirit. Special thanks to the Teruah Jewish music blog
for reminding me about My Father My King by Mogwai. I originally found this song back in the olden days when Napster was still around and popular. I used to type in key words like "israel" or "jewish" and one day I found something called Jewish Hymn, which is officially entitled My Father My King. It is Mogwai's version of Avinu Malkeinu and is is about 20 minutes long. Avinu Malkeinu actually translates at Our Father Our King.
