Brahms' lifelong preoccupation with the solo voice can be heard to great effect in this sixth volume of his complete songs. The ghostly and dreamlike opening of the Four Duets, Op. 28 and moods of desolation and loss in the Nine Songs, Op. 69 are linked by the unusually disparate subjects in each set, while the playful spirit of southern Italy and Spain forms part of Op. 58. The programme ends with great musical beauty, depth, and even touches of crude humour in Five Songs, Op. 72.
