PEK and Yuri Zbitnov lead the Metal Chaos Ensemble, here in a septet rendering of this Boston-area free improvising group that embraces an impressive arsenal of percussive, electronic and acoustic instruments, using unique strategies to yield densely active and eerily surreal music, an incredible excursion through experimental improvisation.

A live recording at O'Culto da Ajuda, Lisbon, during the 2017 CreativeFest #11 from the quartet of Ernesto Rodrigues on viola, Guilherme Rodrigues on cello, Gianna de Toni on double bass, and Vasco Trilla on percussion, a sinuous, curving extended improvisation of subtle shades, with certain rotations more forceful, but always gravitating to quietude.
