Animal Collective came to mind for me. There came a point when, through listening to their god-awful last two albums, I questioned whether they’d ever actually been good (thankfully, Feels, Strawberry Jam and MPP still stand up really well)…and this was underpinned by seeing them warble through a live set. It felt like they were critical champions in 2009…and now they’re met with derision.
However, both Deakin and now Avey Tare have released very sold albums recently…and that last AnCo EP was better…maybe they’ll be back.
What other bands fit this criteria?
