Last year I rediscovered Pulp. As a teenager in the mid-late 90sI thought they were okay but put them in with Blur and I don’t really go in much for the overly upbeat Britpop stuff, though I did like a couple of their hits. But decades later I appreciate their clever lyrics and general artistry/ear for a tune a whole lot more.
Another for me is Bjork. I could see the talent back in the day but found her voice a bit grating and melodically all just a bit random. Now two/three decades on and I get why she’s considered by many as one of the greatest popular musicians of all time.
