Good news. I had the chance to speak briefly with a member of Ensemble Inegal. Nibiru will release a recording of the Missa Purificationis, together with the Litaniae Salus Infirmorum and the Miserere. Next month, according to him.
By the way: the concert of Ensemble Inegal in Templin last Saturday can be heard on Deutschlandradio Kultur (http://www.dradio.de) next Saturday at 20.40. I can recommend it highly!
