""Lux" opens with Amper's big, powerful, exuberant "Spelpuma", combining several melodic themes that hint at Bach, baroque and Swedish tradition, with the whole team on violins, cello, double bass, drums and percussion. Then into the traditional "Halling Etter Bråta Per", learned from Ellika Frisell, in which the nyckelharpa sounds remarkably hardanger-fiddle-like - quite a feat with a keyed instrument, but Amper wasn't named world champion for nothing. And, while she's always though of herself as primarily a nyckelharpa player, she's a fine singer. The song she wrote and performed for the big-audience TV Lucia celebration, "Ljus I Mörkrets Tid", is here, a beautiful, serene secular paean to warmth between people in this time of cold and hate, (...) and more, including a stately polska on four nyckelharpas, all played by Emilia, that shows how well the instrument covers the whole range of a string quartet"
