Profiles Maori musicians and entertainers who have been largely unrecognised for their contributions. Tonight: The evolution of Ratana music from the Te Reo brass band, to the Remnant Set.For almost a century, Rātana have been teaching music to Māori, but have often been overlooked despite their contribution to our local music industry. Rātana introduced Māori to Brass band concepts, and reading and writing music is a tradition that continues to this day. In Episode 1 of Unsung Heroes we follow the evolution of Rātana music from the Te Reo brass band, to the Remnant Set, and contemporary artists like Ruia Aperahama. (SERIES PREMIERE)
