In truth, I know absolutely nothing about Grime/Hip Hop etc so couldn’t make a judgement call on that.
However, I’ve been in bands and I also promoted bands/organised gigs for years too – and most bands I came across, in my experience, were middle class. They could afford to doss around unpaid or on low pay for years. They’d start at university, graduate then just carry on the lifestyle and call it ‘art’.
There’s hardly any money in that sort of music - most gigs were unpaid or paltry expenses. Even if you got a deal, you’re still on the breadline. I never succeeded financially with it (most I made was from organising gigs but that could be dicey as ****) and friends who did, took a long time to do so and I still wouldn’t call them well off (apart from they live from making music and tour Europe regularly etc – jammy bastards).
I remember when I was about 20 and naïve. I was speaking to a singer from another band who was a lot older than me (he’s a fairly well known TV/music journalist these days) and I told him, thinking I was being modest in my ambition, that ‘I just wanted to make a living from music’.
He laughed – ‘no chance’.
It’s easy to put your music out there these days but very hard to make anything to live on from it.
