North meets south, dark meets light, and believe us: sparks will fly. Imagine the Earth and the Sun as seen from the Moon; an eclipse in reverse, and the deep shadows and unimagined colours as solar rays glow and flex. That’s the idea behind Antiphaser; an astonishing new concerto for electric violin from the imagination of Mexican composer Enrico Chapela, unleashed today by one of the mos adventurous of British violinists. In orbit around it, Mihhail Gerts conducts two unsung masterpieces from his native Estonia. Swansong by Arvo Pärt captures twilight with the clarity and emotional depth that have made him the world’s most performed living composer, now in his 90s. And to finish, discover the beauty, defiance and raw power of Eduard Tubin, Estonia’s greatest 20th-century symphonist.
