I’d be incredibly surprised if she was in the headline conversation at all. At best I could say a high Pyramid slot but I reckon maybe Other headliner against a rock act like Fender or even Other sub (where I have her in my predictions). I’d say Gracie Abrams is pulling similar if not better numbers to Tate and she was third down on the Other last year.
Sophie Williams (journalist and Mercury Prize judge) was on Huw Stephens' roundtable last week, said she'd love to see Overmono headline Green Man. Does feel like it's bound to happen. 2027 is surely on the cards seeing as they're about to release a new album
Saw em live back in march, and they were bloody marvellous - all flames, ghouls and skulls on sticks. And so tight musically! (i'm a Pleasure To Kill man in terms of albums, mind)
