When I look back at the 80s and 90s I realise how much U2 stood alone.
I was thinking about the very biggest bands from the 80s and the 90s and a lot of them fall into that hard rock/heavy metal grouping – Metallica, Guns N’ Roses, Aerosmith, Def Leppard, Bon Jovi, AC/DC, Pearl Jam and Nirvana (okay, those last two are grunge, but they’re heavy-ish). So all those bands enjoyed a massive overlap in audiences and a sense of safety in numbers. U2 had no such close peers, they were paradoxically massive and isolated and that suited them just fine. But when you look back, it’s kind of remarkable how singular they were and how much they did not really come from a scene or inhabit a scene.
