I have a little bit of Jongen in my collection – and that includes his very Franckian Symphonie concertante for organ and orchestra op. 81 performed by Virgil Fox and the Paris Opera Orchestra under Georges Prêtre on EMI Matrix – but so far I’ve reviewed only the not significant Aria & Polonaise for trombone and piano, recorded on Etcetera KTC 1284, part of Etcetera’s 3-CD collection of the Dutch New Trombone Collective, KTC 1355.
