There's always been a crossover appeal among avant, jazz artists with renegade contemporary classical composers. As with various musical forms, and perhaps life in general, rules are sometimes meant to be broken. String Quartet features a 1979-penned composition by Morton Feldman, recorded by the highly-regarded Dutch group known as the Charles Ives Ensemble.

Triadic Memories is one of Morton Feldman's most popular and frequently performed works for piano. Here, more than is usual in his music, Feldman uses the repetition of patterns and gestures. The repetitions are rarely exact – they are characterized by very subtle rhythmic variations – but almost every gesture, whether large or small, is repeated a few or many times. The repeated figures, while all being quiet and relatively simple and brief, vary in their length, structure, and texture. The unpredictability of the number of repetitions, the asymmetry of the repeated figures, the avoidance of a regular pulse, and the subtlety with which Feldman alters the repetitions keep the music continually intriguing for the attentive listener.

Few atonal piano compositions are so amenable to generate new meaningful, extremely sombre soundscapes as ‘ Triadic Memories’, according to different modalities of execution some would call rendition. This one execution, excruciatingly slow, generates aural hallucinations in the guise of rational insights. Beware of the illusion of order, this Feldman classic piece proves that that is way more harmful, as in pathetically alienating, than the illusion of depth..
