Six pieces developed by violinists Johnny Chang and Keir GoGwilt, with vocalist Celeste Oram joining on three, starting with early music works by Hildegard van Bingen and Orlando de Lassus in a hybrid of musical archaeology informed by modern concepts of repetition, variations of timbre, improvisation, &c, as they seek hidden sound worlds in older notation.

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.

Austrian composer Peter Ablinger wrote this study, which is not intended for live performance, using a violin performing a slow glissando over one octave, here performed by violinist Johnny Chang, the recording then composed in the studio as a proportion canon, virtually layering 16 violins in a study displaying the harmonic interactions of that single glissando.

Two solo installation works from Wandelweiser composer Jürg Frey--"Paysage d'échos" in Aarau, Switzerland, in 2009; and "Equilibre fragile" in in Aarau in 2014--plus Frey's "Streichtrio" performed by Angharad Davies (violin), Johnny Chang (viola) and Stefan Thut (cello); and a solo piano work, "Eyot", performed by Antonio Correa.

The meeting of Johnny Chang (viola), Jamie Drouin (suitcase modular synth), Dominic Lash (double bass), Dimitra Lazaridou-Chatzigoga(zither, and David Ryan (bass clarinet) recording at Bourough welsh Congregational Chapel, in London in 2013, recorded by Another Timbre label leader Simon Reynell, for a unique merging of disparate approaches to ea-improv.

Electronics artist Watkins wrote this piece for resonant spaces, interactive electronics, audience participation & string quartet, here in a special version tuning each string to an odd partial of 60Hz.
