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.

Continuing their exploration of isotopes, here focusing on the unstable element Uranium, the Portuguese Isotope Ensemble led by violist Ernesto Rodrigues presents two stunningly detailed concert performances from the 2021 CSFest XV at O'Culto da Ajuda in Lisbon, with some of Europe's leading improvisers taking on U92 in both "Electroacoustic" and "Acoustic" properties.

With an ensemble of adept improvisers including Luis Vicente on trumpet, Nuno Torres, Jose Lencastre and Bruno Parrinha on reeds, Luis Lopes on guitar, &c, Creative Sources leader and violist Ernesto Rodrigues' Isotope Ensemble examines the element "Helium" in a monumental 44-minute electroacoustic improvisation recorded live at O'Culto da Ajuda, in Lisbon.

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.

Creative Sources collective Isotope Ensemble led by Ernesto Rodrigues performed with a large electroacoustic group continues their investigation of isotopes, focusing on Lanthanum, a soft metal used in flints, through subtly-developing interplay the band, moving as one body, reaching several highly controlled periods of passionate improvisation, contrasting with beautifully serene sections; impressive.
