The Portuguese large improvising ensemble String Theory is heard live during the CreativeFest#12, at O'Culto da Ajuda, in Lisbon, Portugal in 2018, in an extended improvisation of incredible layering and restraint, making an amalgam of mostly acoustic string sources sound electronic and hallucinatory, an incredible achievement in string sonics.

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".

Correctly configured, the Portugese ensemble Octopus is an octet, and though named after the most common of the breed, this 8-tentacled orchestration of strings, flute, trumpet, piano, guitar, electronics and percussion, all using extended techniques, slides deftly and with incredible restraint through a large, detailed dark-water work of electroacoustic improvisation.
