TOC, the trio of Ternoy, Cruz & Orins respectively on keyboards, drums and electric guitar, celebrate fifteen years of free improvisation with this expansive 4-CD set of recordings from the 2021 Spontaneous Music Festival in Poland; Lumen in Budapest in 2021; the 2021 Festival la malterie in Lille, France; and reissuing their 2008 CD on the Circum-Disc label, Le Gorille.

Applying techniques that Michael Pisaro uses in his audio compositions to song formats, this album presents 11 new versions of songs from his 2013 Human Ear Music album, here reworked for clarity and recorded under the artistic direction of the Lille-based pianist Barbara Dang and six members of the Muzzix collective (Bellefont, Cruz, Orins, Pruvost & Pruvost).
