About £1.7m has been spent on refurbishing this illustrious instrument, and it sounds wonderful in Preston's performances of a repertoire designed to show off its versatility. He begins with a spectacular arrangement of the overture to Mendelssohn's St Paul by WT Best, who inaugurated the organ in1871, and proceeds to Schumann's Six Fugues on B-A-C-H, a powerful, substantial half hour. Modern music is represented by William Bolcom's Fantasia on two spirituals, and the range extends to the theatre-organ style of The Brothers Gershwin, Howard Cable's arrangement of familiar tunes. Karg-Elert's Valse Mignonne is in a similar vein, though Joseph Jongen's Sonatas Eroïca is most definitely serious.
