Nell' Ambientes from Poland play ethno/fusion/trance music, using many instruments including didjeridoo, hurdy-gurdy, djembe, bass guitar, harmonica, flutes... They also play with a larger line-up as Gadajaca Tykwa (The Talking Gourd), however, The Talking Gourd is mostly influenced by African music, while Nell' Ambientes is much more trance-oriented. They also call Nell' Ambientes their "export version" and have actually performed outside Poland.
One of their "songs" is about ergot poisoning, which is also explained at the beginning of this video, recorded at St. Nicholas Day Folk Feast. But first I guess I'll have to provide some rather rough translation...
Do you know that story
That after eating rye
A strange dance was danced,
St. Vitus Dance
Strange things happened
'Cause after eating bread
Some went to hell
And others to heaven
St. Vitus Dance
inexplainable state...
Inexplainable, incomprehensible,
impenetrable, unforgettable
In complete unconsciousness
Strange things were seen
St. Vitus appeared
Or some other illusion
When grain was covered by fungus
You were seen, o God
Right after eating
In a common revelation
