For the majority of artists, making music is financially unsustainable. According to a census conducted by the Musicians’ Union, nearly half of working musicians in the UK earn less than £14,000 a year from their craft, while a further half have to sustain their careers with other forms of income. It’s easy to imagine that these are the aspiring performers making tunes in their bedrooms and moonlighting as bartenders, but even household names are turning to alternative income streams.British singer Kate Nash announced on Thursday that she would start posting pictures of her bottom on adult website OnlyFans to raise money for her tour. The Foundations singer has nearly a million monthly listeners on Spotify, and is playing all across the UK, including a sold out gig in London, but says that touring is a loss making exercise.
