Final suggestion from me for now but Die Spitz would be excellent! Always look fantastic live, their set at Coachella this year was awesome and they seem to be on the up and up (playing Download next weekend, supporting Foos at Anfield) so wouldn't be surprised to see them about.
One of my personal favourite bands at the minute - MUNA. Was very surprised not to see them booked in 2023 with their last album but hopefully they'll be around next year. Very fun new album from these guys and, as aforementioned, another standout for me at Big Weekend.
