To pay some depth that I owe you by now,posted are singers from Slavonia region,north-east Croatia
Ižipci from Topolje near Draž,northeast Croatia near Magyarorszag border



with addition of east Slavonian bagpipe



This region is near Magyarorszag so tune are common from both side of the border.Note that bagpiper is magyar Andor Vegh playing croat tune.He is also member of croatian root folk music group Kries.

For those, who don't know what is "Magyarorszag" - we call it "Ungari" here.

And because OP was a bit shy, I'll pass his question to Lauri:
DO YOU HAVE ANY KNOWLEDGE OF EESTI TORUPIL?

I can say only:
- Very scarce, but you SHOULD put some examples to our English forum and ask Lauri. He is quite an expert of "torupill". It means a "pipe instrument" in modern Estonian, but may be more likely derived of the name of our thunder deity Tooru, (who has counterparts both in Scandinavia - Thor; and Siberia - Toorum) The meaning of the word "toru" is probably originated from it's pipes.
