Conductor Christoph Eschenbach's music-making is characterised by its energy and commitment. His Prom on Friday, with the BBC Symphony Orchestra, was no exception, in music by Barber, Tchaikovsky, and French composer Marc-André Dalbavie, whose work Color received its British premier.

Color transformed the orchestra into a single instrument, as the piece slowly expanded from a haze of string sound into a visceral dance then contracted again. Midori was the soloist in Barber's Violin Concerto, and her performance hinted at melancholy depths beneath the pastoral surface of the first movement, although the finale was a bravura display.

Under Peruvian conductor Miguel Harth-Bedoya, the BBC Concert Orchestra celebrated rarely heard music from Mexico and Argentina. Works from the early 1940s by Jose Pablo Moncayo and Galindo Dimas created a riot of gaudy colours but sounded overblown. However, pieces by Astor Piazzolla revealed the riches of Argentinean music. Horacio Roma was the stylish soloist in Piazzolla's Concerto for Bandoneon, and Piazzolla's Tangazo: Variations on Buenos Aires, a miniature orchestral tone-poem, was a vivid reflection of urban life in Latin America.

· Prom 63 (Eschenbach and the BBC Symphony Orchestra) is on Radio 3 on Friday at 2 pm.
