One of the core Creative Sources trios of Ernesto Rodrigues on viola & crackle box, João Madeira on double bass and Jose Oliveira on percussion, is extended to a quartet with Netherland's New Wave of Jazz/Vidna Obmama archtop guitarist Dirk Serries, presenting the 9-part "Dripping" series of free chamber-oriented lowercase improvisation.

Working together in a variety of setting and ensembles--Variable Geometry Orchestra, Suspensao, groupings with Hernani Faustino & Jose Oliveira, with Michel Stawicki, and with onsieur Trinite--the core trio of Ernesto Rodrigues on viola, Bruno Parrinha on bass clarinet and Joao Madeira on double bass, is heard in three studio improvisations of dark woods explorations.

The Suspensao octet are heard in this live performance at SMUP, in Parede, Portugal in 2023, blending primarily acoustic instruments with electric guitar and analog synth, using a reductionist approach to highly concentrative and suspenseful free improvisation, their long-running collective history allowing an impressive level of articulation and control through the integration of diverse voices.

Improvising over strings, winds & percussion from the Portuguese quintet of Ernesto Rodrigues on viola, Guilherme Rodrigues on cello, Joao Madeira on double bass, Bruno Parrinha on flute & bass clarinet and Monsieur Trinite on percussion, in a studio session of active, often pointillistic interaction offset with periods of introspection, reflecting concepts of Baudelaire & The Surrealists.
