last summer I took part in a 5 day work shop run by Candida Valentino & Michael Ormiston.
For anyone who wants to try out throat singing or overtone. I would thoroughly recommend their workshop.
Alternatively go and check them out performing.
Here are their upcoming events http://www.soundtransformations.co.uk/concertsmain.htm
