Opening the outdoor program at Komuna Warszawa is Microplastics, an expectedly unhinged, rock-inspired collaboration between three of the UK's most distinctive artists: aya, Jennifer Walton and 96 Back. Then the mood will shift immediately for Armand Hammer, the long-running New York City-based duo of gifted rappers billy woods and ELUCID who have made waves with their run of gritty, lyrical albums like last year's 'Mercy', a collaboration with iconic beatmaker The Alchemist.

To round off the evening, Polish producer Przemysław Jankowiak (aka 2K88) will reconvene with British rapper-producer Rainy Miller, London-based art-pop innovator Lauren Duffus and dancer-producer Bianca Scout to celebrate the release of their debut collaborative album, a blend of smoked-out, soulful vocals, hazy soundscapes and tempered beats that's due to appear a co-release on the Unsound label and Fixed Abode. The project is supported by the British Council as part of Selector After Dark.
