I too discovered Kullervo in the early 1970s via that first wonderful Berglund set - I still have the LPs somewhere (don't ask me why). I was studying at the time at Bristol Poly and Berglund did bring the Bournemouth Orchestra to the Cplston Hall - but never Kullervo.
PS do any of you have the very rare EARLIER LP set of Kullervo - Jussi Jalas I think. Now THAT I would also like to hear.
I never thought about Kullervo as mature or immature. I just embraced it as a glorious piece of music and have been hoping at long last to be able to hear it live.
All being well I will be at the Royal Albert Hall in London on 29 August 2015 to hear Kullervo live for the first time alongside En Saga (another work I have never heard in concert, believe it or not): PROM 58: Johanna Rusanen-Kartano (soprano), Waltteri Torikka (baritone), Polytech Choir, BBC Symphony Chorus (men's voices), BBC Symphony Orchestra, Sakari Oramo (conductor).
There is something kinetically driven and even possessed about the choir when they sing the words "reki rasasi". I will be on the edge of my seat ready for that (among many) moment.
