Nils Meisel and Luís Figueiredo are two artists from Porto, together they created Preto Marfim, a experimental music group exploring "horizontal" soundscapes heavily influenced by early byzantine and Orthodox music.
For One Drone Day Preto Marfim is going go perform a version of a composition created for the installation entitled: "And so on... and so on..." a long spacial drone with many layers of sound and splendorous landscapes.
