The trio of reeds, double bass and piano has a long and distinguished history in advanced jazz and other improvisational musics. From Jimmy Guiffre’s innovative trios to the more recent trios of Paul Bley, Evan Parker and Barre Phillips, or Ken Vandemark, Havard Wiik and Haker Flaton, the drummerless trio has the dynamic range and palette of timbres to produce a kind of improvised chamber music of introspection and expression. Istinti Ragionati, a trio recording featuring Roman reed player Marco Colonna on clarinet and bass clarinet, and the Sardinians Silvia Corda and Adriano Orrù on piano/prepared piano and double bass, respectively, is an outstanding demonstration of the range, subtlety and power this type of ensemble is capable of.
Although fully improvised, the music shows the kind of balance and organization ordinarily associated with small-ensemble, composed chamber music. This is most immediately apparent in the trio’s supple control of texture, which arranges sounds in order to allow space for individual and ensemble passages to develop in an uncluttered environment. While often abstract, these passages retain a grounding in melody even when the vocabulary turns atonal and the dynamics veer into the heated expressionism of free jazz. Colonna often favors a long line that moves easily between pantonality and a lyrical modalism; when not providing harmonic support for tonal episodes, Orrù takes the bass into the rich territory defined by free counterpoint and pure timbre. As the hinge between wind and strings, Corda deserves special mention. She’s capable of binding the two other voices with suggestive harmonic fragments, or braiding them by serving as a third line within the polyphonic whole. In addition, her harmonic clusters and phrasing do much to flavor the group sound with the cerebral astringency of the classical avant-garde.
This is superbly thought out improvised music whose spontaneous formal sense makes the title—loosely meaning “rational instincts”—seem particularly well-chosen.
