Really enjoying listening to some Tibetan tantrik ritual music. I use it to accompany some of the sadhana work I do, or have it playing in the background when I am studying or writing. I have a few albums, but also found some links online with good material. For example, check out this link to a 19 minute sample of very powerful, evocative ritual sounds. Conch shell, human thigh bones, cymbals, drums… remarkable, unique sounds that have an otherworldly feel and transport me to deep realms.
