There was outrage in Manchester yesterday when a popular mural of late Joy Division frontman Ian Curtis was painted over with an advert for the debut album by fellow local musician Aitch.Unveiled in 2020, the painting of Curtis on Port Street in the city centre by artist Akse P19 was originally created to mark the start of the Manchester music and mental wellbeing festival Headstock that year. As well as paying tribute to Curtis, it also promoted mental health support service Shout and has subsequently become a popular landmark.So there was anger yesterday as a picture circulated on social media showing that the mural was being replaced by an advert for Aitch, apparently commissioned by Amazon Music.“Absolutely gutted to see our Ian Curtis mural painted over”, said Headstock on Twitter.
