Young Portuguese unit, Red Trio, take the essential energies and instrumentation of a progressive piano trio and unhitch them from conventional notions of metre or melody, creating tumultuous and decidedly free music that nevertheless bubbles with an irrepressible sense of forward motion and implied, internal tempo. This second collaboration with UK saxophonist John Butcher – following on from 2011's Empire – wastes no time in stirring up a swift, swirling vortex of intense activity with pianist Pinheiro's imagination shooting off into brief, blazing ideas like rockets in a deep blue sky, while the bass and drums team of Faustino and Ferrandini crash and rage. In this context, Butcher – often stereotyped as a clinical, cerebral stylist – lets rip with some muscular tenor technique, spitting out restless blasts and brays and even flat-lining into the kind of trilling trance-growl Coltrane employed from around 1965 onwards. It's turbulent European free-jazz for turbulent times. We need it.
