This Stabat Mater, from the album Bogarodzica (Mother of God) is a Polish anonymous melody by vocal ensemble Jerycho. The songs  on the album have been dedicated to Mother Mary. Mr. Marcin from Poland was kind enough to point me to this album. Indeed, it’s a very special edition. The CD-booklet is a real book of up to 60 pages! It’s a shame I can’t read Polish!
