There’s more captivating playing from violinist Linus Roth on volume 22 in Hyperion’s Romantic Violin Concerto series, a melodic voyage of discovery through works from two Danes, Eduard Lassen and Rued Langgaard, and the Prussian Philipp Scharwenka. Langgaard’s is a single-movement piece from 1943, nostalgically recalling an earlier age of compositional innocence. Lassen’s is more muscular, but overflowing with delightful melodies, while Scharwenka’s is the most sweetly pleasing, with a deeply lyrical central andante. Roth plays with almost missionary zeal, he and the BBC Scottish Symphony Orchestra, under Antony Hermus, making a convincing case for these works to be more widely performed.
