This supergroup of strings--16 musicians on violins, viola, cellos, double basses, piano, psaltery, zither, and guitar--in an intensely restrained collective improvisation recorded live at O'Culto da Ajuda, Lisbon, Portugal in 2017, as String Theory's 4th album continues their title themes from the physical universe named here for the rare metalloid "Tellurium".

An incredible example of Creative Sources/Ernesto Rodrigues' large electroacoustic ensembles, blending acoustic and electronic sources in slow moving and subtle improvised works of a large scale, here with 12 musicians layering string, brass, keys, percussion, synth and computer into a mysterious harmonic and hallucinatory convergence of powerful intention.
