In a compact and quick-read format, Missing Music collects the latest narratives from Brennan's field-recording treks. This edition features a greater emphasis on storytelling and an even greater abundance of photos from his wife, Italian-Rwandan photographer/filmmaker Marilena Umuhoza Delli. Together, they meet the elderly shamans of the world's most musical language, Taa, a tongue that sadly is dying, with fewer than 2,500 speakers left. The duo travelled the most remote roads of Botswana to find the formally nomadic people now relegated to small desert towns. In Azerbaijan, Brennan and Delli ascended to the mountainous Iranian border to record centenarians in scattered villages of the Talysh minority, where the world's oldest man reportedly reached the age of 168. The result is the only record ever released to feature the voices of singers over one-hundred years of age. Among other tales, Brennan also updates the saga of the Sheltered Workshop Singers following COVID, including the tragic deterioration of his sister, Jane. Arising from the more than forty records that Brennan has produced over the past decade from underrepresented nations such as Comoros, Djibouti, Romania, South Sudan, Suriname, and Cambodia, Missing Music serves as the newest suite in the multiverse symphony of the world's most ignored corners - the places where countries expire and the 'forgotten' live.
