Johannes Brahms' Liebeslieder-Walzer (1869 & 1875), Op. 52 and Op. 65, are a cheerful, short, witty set of songs full of anger, joy and rejection. These part-songs are accompanied by one piano, with four hands and any number of voices can perform any selection. These enchanting works are performed as part of Barbara Hannigan's Momentum project, which teams up new talent with more established performers. Here, tenor Nicky Spence, soprano Mary Bevan and pianist Joseph Middleton are joined by three rising stars (mezzo-soprano Fleur Barron, bass William Thomas and pianist Dylan Perez) in these love songs said to have been motivated by Brahms's unrequited love for Clara Schumann.
