“Don’t ask me what I mean, ask me what I’ve made” – inspired by this motto, the documentary accompanies the American composer Alvin Lucier (1931 - 2021) on concert travels to The Hague (Netherlands) and Zug (Switzerland). Lucier explains and comments on his œuvre – from his early live electronics performances (MUSIC FOR SOLO PERFORMER,1965 and BIRD AND PERSON DYNING, 1975) up to the premiere of his ensemble piece PANORAMA 2 in 2011. One of Lucier’s key works, I AM SITTING IN A ROOM (1969), is introduced as a central structuring device in the film.  At home in Middletown, Connecticut, Lucier offers rare insights into the beginnings of his pioneering works, his time as a member of the Sonic Arts Union, his relations with John Cage and David Tudor, as well as his teaching practice at Wesleyan University.
