The very wonderful Frankie Armstrong has been responsible for a great many people experiencing the absolute joys to be had by singing – myself included!!!
She has been running Voice Workshops for non-singers for many a long year (I did my first in 1984) and she uses the full-bodied, open-throated style and techniques of Eastern European and African cultures (and most non-Western, really). I believe she co-ran early ones with Ethel Raim, of The Pennywhistlers fame and collector of Bulgarian material.
Frankie is a very warm, caring, generous, deep thinking but fun-loving, person and remains friends with a large number of her workshop participants from around the world.
I remember being overjoyed to discover Frankie's singing in the very early 70s, because far too many "folk women" sang like Shirley Collins (or worse).
Enough said.

Cheers! R-J
