In 2005, Swedish trombonist and bandleader Nils Landgren assembled a few musician friends for a Christmas concert in a Stockholm church. A recording of it scored a surprise hit, especially in Germany, and they did it again two years later. This is the fourth edition of what has now become a sell-out concert series with platinum-selling albums. The secret lies in the combination of simple intimacy, polished musicianship and a programme full of subtly chosen surprises. Duke Ellington, Gustav Holst, J Fred Coots, traditional Swedish and German carols – they’re all brought together with just the right touch.
