Here's a recording I made and put on you tube of the Hundred Handprint Healing Chod ritual. It was recorded around 2007-9 (I can't remember which of the sessions I recorded) at Lama Wangdu Rinpoche's gompa in Tusal, Boudha, Nepal. It's accompanied by a set of photos mostly taken at he gompa but not all from during that session - many during the Rinchen Trengwa Chod.
The first minute and half is sllent and then the monks (having completed the Khandro Gegyang Chod) start the Hundred Handprint... at 6 min 28 seconds - it really gets going! https://www.youtube.com/watch?v=XDxlS-bkfX8
