Thanks to blog of SDH have I info about other czech ensemble, with focus on gregorian chant. On the website of Schola cantus Gregoriani (in czech language only) there is description of the ensemble and its repertoire, photos, audio samples, events announcements and some links to other sites.
International festival of gregorian chant should be hold from 18. — 21. october 2007 in Bratislava, Slovakia. Organizer is Bratislava Choral Agency. Quoting from the website of the festival:
The mission of the event is to support new interpretation of Gregorian Chant in line with the latest Gregorian semiology knowledge. Gregorian Scholas are eligible to join the festival either as non-competitive or competitive scholas. The program for competitive and non-competitive scholas is the same.
On the website you can find competition rules, entry requirements, festival schedule, application form and contact informations. Missing is info about Jury.
There is a contradiction between entry requirements and the mission of the event in my opinion. It is hard to consider as support of anything (except of organizer’s benefit), if every entrant pays for all their costs and Registration fee in addition.
Prague (Czech Republic) chamber woman’s vocal ensemble Schola Benedicta has after longer pause again its website. You can find there infos about history of the ensemble, photos and samples of concert activities, current news, responses and recensions… (in czech language only — so far)
Art director of the ensemble is Jiří Hodina, former member of Schola Gregoriana Pragensis, graduated from Paris conservatory (Conservatoire Nationale Superieur de Musique de Paris), the program Conducting Gregorian Chant. Under his direction we held our workshop in 2005. I would like to draw your attention to his texts about chant.
