This chapter focuses on the new sound economy that Pentecostalism brought to Rwanda after the genocide. It considers a wide range of Pentecostal sound practices – from noise-making to praise and worship to Pentecostal radio – and shows how sound was understood to be key to inner and outer transformation. Pentecostals drew a distinction between ‘godly’ and ‘secular’ media, which allowed some young singers to become ‘gospel stars’. This chapter equally focuses on the materiality of Pentecostal sounds – the work that sound does outside of its discursive properties – and places this within the wider sonic context of post-genocide Rwanda. The RPF state has increasingly cracked down on noise – associated both with the new churches and nightclubs – and in 2018 closed thousands of chruches across the country. Perhaps ironically, despite their differences, the new Pentecostal churches and the RPF state share a conviction of sound’s transformative power.
