Presented by Petroc Trelawny. The BBC Symphony Orchestra return to the Barbican Hall in London for a concert in which they perform works spanning two centuries of the intertwined musical stories of Hungary and Austria. The concert opens with Gyorgy Kurtag's ...quasi una fantasia..., an overt reference to Beethoven's Moonlight Sonata, which is also titled 'quasi una fantasia', but a piece that uses the full spatial possibilities of the Barbican Hall with members of the orchestra spread around the auditorium. It is followed by Mozart's Piano Concerto in E flat, often known as Jeunehomme, and penned when the compser was working in Salzburg, for a visiting female French pianist - Miss Jeunehomme. Kurtag: ...quasi una fantasia... Mozart: Piano Concerto No 9 in E flat, K271 (Jeunehomme) Jonathan Biss (piano) BBC Singers BBC Symphony Orchestra Robert Spano (conductor) Followed by a focus on Sing Hallelujah, a UK-wide celebration of choral singing inspired by Handel's famous chorus.
