A really unique take on the form of free improvisation – one done at a distance, during the global pandemic in 2020 – but at a level that's very different than anything else we've ever seen on record! The "correspondence" in the title is a reference to the process of the album – as each artist would first record a solo, then send it to the other, who would then respond with a solo of their own. This means that the record is all solo performances, not duets – but done at a level that's still very resonant with the work of the other artist – although at a remove, which maybe allows for even deeper concentration on a musical response! Rafal Mazur plays acoustic bass guitar and Agusti Fernandez plays piano – but the sounds of the instrument are very different than usual – filled with all these textures and really striking sonic possibilities.
