Rachmaninov’s Symphony No. 2 – a passionate, unashamedly emotional score from a man who once declared himself ‘completely under the spell of Tchaikovsky’ – is paired here with a kaleidoscopic tour of the orchestra by the Ukrainian composer Ivan Karabits, father of the Bournemouth Symphony Orchestra’s long-standing Chief Conductor, Kirill Karabits. Premiered in 1981, his Concerto for Orchestra No. 1 was written to celebrate the 1,500th anniversary of the founding of Kyiv in chiming bells, fanfares and marches: a sonic snapshot of a city in happier days. Horn virtuoso Felix Klieser makes his Proms debut with Mozart’s sunny Concerto No. 4.
