Right, I'm a big fan of Tubin ever since I accidentally heard his Fourth in a Radio broadcast, back in the early 1980s. His cycle of ten symphonies is among the very best in the 20th century - on equal par with e.g. those by Vaughan Williams, Nielsen, Sibelius, Shosta, Braga Santos.
Both cycles available (Järvi and Volmer) are very fine. And I was lucky enough to attend performances of the Fifth and Sixth here in Utrecht (both times under Volmer) as well as a sort of premiere of the 11th (first part only, finished by Kaljo Raid at the request of Järvi) under Järvi, with the Royal Concertgebouw Orchestra in Amsterdam, somewhere around 1990.
For some inexplicable reason, but Jezetha seems to be offering a clue, I never really came to grips with the Fifth. But I highly enjoy all the others, and especially 1, 4, 6, 7, 8, 9, 10, as well as both violin concertos, the double bass and balailaka concertos, Music for Strings, several 'Estonian' suites, a.s.o.
Btw, did anyone hear the complete Kratt ballet music, released last year by Alba, also under Volmer? (I bought it, but didn't find time to listen, yet).
