Conductor and Naxos artist Marin Alsop discusses Robert Schumann\u2019s four symphonies in the wake of her recordings of the works as reorchestrated by Mahler (8.574429\xa0and\xa08.574430). Following observations about instrumental developments of the time, Mahler\u2019s myriad tweaks to the score, and the somewhat bipolar flavour of the music (with counterpoint always at hand as a periodic stabiliser), she moves on to a detailed appreciation of each symphony, demonstrating Schumann\u2019s distinctive contribution to the development of the genre \u201cwith one foot in the past, and one in the future.\u201d
