Part of Japanese composer Taku Sugimoto's Solo for Strings series, these works focus on bowed stringed instruments played only with natural harmonics, arranged with clarinets and flute, using long tones and repetition that allow the performer decisions on their length, performed by a Berlin-based octet including Catherine Lamb, Johnny Change, Samuel Dunscombe, &c.

Three concisely plain compositions for guitar, two solo and one trio, are played only with open strings or natural harmonics, where all the tunings are respectively irregular, written by Tokyo-based guitarist and composer Taku Sugimoto and performed and recorded in St. Petersburg, Russia by guitarists Andrey Popovsky, Denis Sorokin and Alexander Markvart.
