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.

The Lisbon String Trio of Ernesto Rodrigues on viola, Miguel Mira on cello, and Alvaro Rosso on contrabass continue their recent string of collaborations with a fourth player, Portuguese tuba player Gil Goncalves joining to addd a unique complement to their strings, as Goncalves adds bass, blats, growls and unique timbres of upper register low brass.

Two CDs representing two extended improvisations of the IKB Ensemble with slightly different personnel, with each ensemble slowly unfolding an amazingly textured work of acoustics and electronics with strong intent and incredible technique, balanced by close listening and attention to detail; an excellent 21st century improvisation orchestra captured live.

A large group under the direction of violinist Ernesto Rodrigues (also on harp, metronome & objects) in 4 extended improvisations of great suspense and tension through sound and silence.
