NEKO3 is a Copenhagen-based contemporary music ensemble consisting of three members: pianist Fei Nie and two percussionists Lorenzo Colombo and Kalle Hakosalo. The ensemble is working towards the creation of a new musical language and repertoire, building a narrative and concept for each concert and aiming to provide unique experiences for its audiences. NEKO3 is continuously collaborating with composers and other creators of art, focusing on the interplay between images, electronics, videos, lights, and seeking to integrate music, visual art, installations, body performance and other forms of art into one conceptual whole.

They have given workshops and presentations at ie. the Royal Danish Academy of Music (DK), Hochschule für Musik und Theater Hamburg (DE) and Kungliga Musikhögskolan (SE). Their Micro-workshop initiative aims to provide young composers and other artists with an open platform to freely experiment on new ideas together with musicians, as well as making contemporary music and art accessible to all audiences.
