This is not the Johann Krieger whom keyboardists may know for his six keyboard partitas (never completely recorded) but is that one's elder brother Johann Philipp Krieger. This Krieger's violin sonatas convince through their expressiveness and freshness. Parnassi musici recorded the twelve sonatas in their proper order, and those sonatas seem to be getting even better from sonata 7 on, IMO.
Review from here: Johann Philipp Krieger was one of the leading German composers of his generation. He studied under Rosenmüller and Volpe in Italy and later served as court music director under Johann Adolph I in Weißenfels, holding this post until his death.
In 1688 he published the VII (sic) Sonate a due Violini (and basso continuo); in its form this work reflects the stylistic influence of the Northern German string tradition, which, in turn, is stamped by English consort music. The irresistible appeal of the sonatas rests on the modern flair of the virtuoso treatment of the violins as well as on the remarkable variety of their themes and vibrant affective shifts. Italian influence is also very much in evidence. Once again the Parnassi Musici ensemble demonstrates its knowledge of the fine points of baroque performance practice in a spirited and imaginative interpretation.
