Galas are tricky things to get right. The temptation is to try to include everyone and everything, with a tendency to overegg the pudding. This concert was the closing gala of the From-Sweden festival, which comprised more than 30 events, bringing the often-unknown delights of Swedish music to UK audiences, complemented by their British counterparts.

The programme might have profited from firmer editing. By the time it had extended itself - with the aid of unscheduled items and too much talking - 45 minutes beyond its advertised finishing time, some of the audience were on their way home.

Apart from its classical tradition, which the series has valuably promoted, Sweden has a thriving folk scene, represented here in songs and dances delivered with brio by the trio Frifot. Their vocalist Lena Willemark also sang an authentic herding call, somewhat duplicating the first piece on the programme, by Karin Rehnqvist, which set sopranos Ulrika Bodén and Marie Axelsson herding away wildly at the extremities of their range to a quasi-Wagnerian timpani accompaniment.

The popular tradition of the troubadour featured in a set by Sven-Bertil Taube who performed songs by his father, Evert, to his own laid-back guitar accompaniment.

In the second half, Anne Sofie von Otter's intricately imagined performances of songs by 20th century composers such as Peterson-Berger, Sigurd von Koch and Bo Linde revealed hidden treasures to Bengt Forsberg's immaculate accompaniment. She went on gamely to some Irish folk songs, one from the musical Kristina fran Duvemala by Benny Andersson (of Abba) and another by protest singer Mikael Wiehe.

There was also a powerful performance of a Lennox Berkeley miniature by Forsberg and cellist Mats Lidström, and Vaughan Williams's Serenade to Music, featuring 16 mainly British singers, which the Wigmore's departing artistic director Paul Kildea conducted in his own slimmed-down arrangement. A great deal to enjoy, but too much in one go.
