"Letters from Nowhere" is both a book by Jonas Mekas and a book about Jonas Mekas. The first definition any reference gives about him is "the godfather of New York avant-garde cinema." However, this Lithuanian-American poet, writer, director, critic, and producer is much broader and deeper than any single description. This is evidenced by his "Letters from Nowhere," a series of notes on society and culture, on land and humanity, on small languages and peoples, as well as recollections from friends and a critical essay on his work.

In parallel, photographs by his friend Arūnas Kulikauskas and frames capturing Mekas himself provide a vivid representation of the artist's surrounding environment and inner world.
