Martin Welzel, who also performs on Volumes 6 (8.557338) and 8 (8.570455) gaining American Record Guide’s praise as ‘authoritative’, performs on the splendid Johannes Klais Organ in Trier Cathedral. Although a Catholic, Reger nevertheless drew on the Lutheran tradition’s rich store of chorales, the inspiration for his many preludes, fantasias and other works. Whether pulling out all the stops or exploring the instrument’s more delicate colourings, Welzel demonstrates here why Max Reger is regarded as the greatest German composer of organ music since Bach.
