Composer Marti Epstein’s Nebraska Impromptu is a collection of works highlighting her writing for small ensembles featuring clarinet, played here by Rane Moore. The pieces on the album span 2001-2017; although each has its own individual sound, all share a consistent aesthetic based on the unhurried deployment of mostly quiet, discretely bounded events made up of tightly aggregated instrumental colors.
Oil and Sugar (2016), for piano, clarinet, flute, and violin is exemplary. The piece’s basic elements consist of a series of brief motifs within a restricted range of harmonic movement; Epstein intertwines them among the four voices in a way that dramatizes to good effect the timbral differences of the similarly compassed winds and strings. By relying solely on clarinet, oboe, and violin, Komorebi (2017) displays this effect even further. The title track, 2012’s Nebraska Impromptu for piano and clarinet, plays with contrasts of range rather than color, as the clarinet takes the role of middle voice in between the piano’s upper and lower registers. Liquid, Fragile (2010) for clarinet, violin, viola, and cello is a broken-textured piece that uses long silences as structural supports dividing gently drifting sonic events. The earliest and longest work represented, the twenty-seven-and-a-half minute-long See Even Night from 2001, is a subtly subtractive piece for clarinet, viola, and piano that begins with a relatively dense polyphony of short, repeating, overlapping motifs and then gradually develops through a simplification of lines and opening up of overall textures.
