Kairos is an ancient Greek word meaning the right or opportune moment (the supreme moment). Kairos 4tet was born out of a desire to explore times past, present and future, creating music with a sense of space, between the competing worlds of written melody and in-the-moment improvisation. The band play the distinctive compositions of saxophonist Adam Waldmann, who has been described as "a young master in the making" by Time Out and a "precociously talented composer and player" by AllAboutJazz. Despite comparisons to some of his musical idols including Wayne Shorter, Charles Lloyd and former teacher Julian Arguelles, Waldmann's unique voice and approach on his instrument make him one of the most distinctive saxophonists in the UK.
