I wouldn’t be surprised if it was £425.  If I recall there was a significant jump about 10 years ago and with the prices of gigs significantly inflating in the last couple of years I can see another big jump coming. 

I think they are just sold out ..... I find it highly unlikely that the entire arena wouldn't go on sale for a band the size of muse straight away.   Theres also some in those blocks on sale on resale sites

Personally, I do hope Fontaines headline next year. Feels like it's their time in terms of the contemporary element - I know 2028 could equally be but I think (and speaking as an old git) they are probably the most significant band to emerge for a good few years, and they've already accumulated 4 great albums, let alone adding 5th, to field a memorable setlist.

Alright fair, I thought she only did BST once. Though I do question how that type of pop show will translate to a stadium.
