Alan Hovhaness : Concerto for Two Pianos and Orchestra Op. 123 No. 2 (1954)
Andante – Largo – Moderato.
Performed by Martin Berkofsky and Atakan Sari with the Globalis Symphony Orchestra conducted by Konstantin Krimetz.
This was originally called ‘Concerto No.10’ but was renamed in the 1980’s as ‘Symphony No. 45 Op. 342’ and the Concerto for Piano, Trumpet and Strings Op.413 became ‘Concerto No. 10’. I am unaware of what changes were made (if any) in transforming this to be a Symphony.
