So I have recently discovered the New World Kirtan podcast. Kirtan is essentially a sanskrit singalong. There's a more detailed explanation at the NWK website. I have yet to go to an actual kirtan myself, but during my teacher training, we did quite a lot of chanting and singing. The director of my yoga studio used to run retreats and so we sang songs in English as well. It is absolutely a fun way to bring energy together.
I like to listen (and sometimes sing along!) to the podcast while I'm doing chores around the house or when I'm preparing for class to help me get into a more relaxed, pleasant state of mind.
