OK Brahms Horntrio op.40 is no hidden treasure. It is a wellknow jewel from chambermusic repertoire. Nevertheless Brahms explicitly asks for a natural horn and not the modern horn which was at his time already well established, there are not so mch ensembles among its interprets which played it consequently on "period instruments".
With the natural horns in Historic Winds III we are able to 😊 to complete the period-ensemble I choose the 1873 Erard-Grandpiano from realsamples which fits with his very warm tone very good to the gentle tone of the natural horn.

Again I cant resist to give our modern instruments their chance and rendered a parallel-recording with the a bit lighter Vienese horn and the much brighter Bösendorfer Imperial. However I love the often surprising results of period instruments, I am at the same time still convinced, that the development of musical instruments has enriched the abilities and the sound of the modern available instruments and so they might offer different colours and musical potential we still can and may ake use of.
