Here is the third instalment of our recordings of the complete organ music of the distinguished Czech composer Petr Eben, certainly one of the 20th century's most significant and prolific writers of organ music. We estimate that the series will eventually run to five discs. (Possibly six, since Mr Eben is currently working on another piece.) For this disc, Norwegian organist Halgeir Schiager has chosen the instrument of Oslo Cathedral. He is joined by a second organist, Kare Nordstoga, for the 'Mutations for One or Two Organs'. These are all major works, most of them not available otherwise on CD.
