When the Gewandhausorchester and Boston Symphony approached Betsy Jolas in the summer of 2018 with a commission, her thoughts turned to the two cities, Boston and Leipzig. She was quite familiar with the former but, though she had dreamt of visiting, had never been to the latter. As she gave her fantasy free rein, imagining what it would be like to explore the city, a “Bach playlist” formed in her mind, providing the soundtrack for her reverie. Leipzig became “Bachville” and she had the premise for her commission: an impressionistic evocation of the city through the music of its greatest musician. In September, Andris Nelsons led the Gewandhausorchester in the world premiere.
Letters from Bachville is not a ”name that tune” piece, but a mosaic of brief fragments which intersect at odd angles. A grand array of percussion, including a thunder sheet, lion’s roar and sizzle cymbals, provides the grout which fills the interstices, with a tolling of tubular bells a recurring motif. Very few fragments quote outright, “Jesu, Joy of Man’s Desiring” being the most readily identifiable snippet. More often, Jolas teases or compresses the material, or simply changes pitch, plays with rhythm, or assigns the fragment to a different mix of instruments. Many – like a trumpet flourish here and a contrapuntal passage there – only allude to Bach stylistically. The relevance to Bach is sometimes so submerged, though, that the smiles and knowing glances exchanged by orchestra members are the only signs that something interesting is going on. Nevertheless, Jolas’ reverie allows each individual to compose the piece in their own way, whether they know Bach or not. Nelsons and the orchestra presented the various tesserae and their distinctive colors within the relaxed flow of a daydream, with loving attention to detail and a sensitivity to the humor which animates many of Jolas’ transformations. The 93-year old composer came down the aisle to shake Nelsons’ hand and acknowledge the audience’s approval.
