Recorded live at CreativeFest #18 in Lisbon, the Isotope Ensemble channels the volatile and fluid nature of caesium through spontaneous improvisation, blending strings, brass, woodwinds, piano, electric guitars, modular synthesizer, electronics, and objects into a dynamic sonic reaction that reflects the element's unique liquid properties that make the isotope pivotal role in atomic timekeeping.

The third Spiegel, or mirror, takes the Portuguese acoustic octet led by violist Ernesto Rodrigue through an extended improvisation and its reflection, captured live at the 2021 CSFest XV, at O'Culto da Ajuda, by performing and recording their performance in a first pass, and then playing over the first improvisation, layering and extending their work.

A reductionist set of spartan improvisation performed live at Casa da Cultura, in Setubal, Portugal in 2021 from the trio of Ernesto Rodrigues on viola, João Silva on trumpet and Andre Hencleeday on piano, applying extended techniques on their instruments in a dark night, quiet but intently close listening conversation from three authoritative voices.

A dynamic and exciting concert captured during the 2018 CreativeFest XII of a conduction by Ernesto Rodrigues leading an ensemble of 28 free improvisors performing on a mix of traditional acoustic & modern electronic instruments, plus a toy piano, with powerful wind & string sections, as Rodrigues directs the musicians into both passionate and peaceful sections.

Recorded at CreativeFest#12 in Lisbon at O'Culto de Ajuda, the 21-piece electroacoustic ensemble Isotope takes on the chemical element Radium in a gripping piece of evolving improvisation, intensely restrained and extremely detailed, orchestrated with cello, baroque violin, double bass, acoustic & electric guitars, zither, psaltery, winds, brass, keys, electronics and percussion.
