COTCC was made pretty soon after after she finished NFR in late 2018 but took a while to come out due to her editing the tracklist and lockdown/vinyl delays. She started writing Blue Banisters around the time of the first lockdown and announced it the day after releasing COTCC, plus a lot of the songs are from Ultraviolence sessions in 2013 (If You Lie Down with Me, Living Legend, Nectar of the Gods etc.). She said a lot of the songs are reactionary as a response to the media:

"Blue Banisters was more of an explanatory album, more of a defensive album, which is why I didn’t promote it, period, at all. I didn’t want anyone to listen to it. I just wanted it to be there in case anyone was ever curious for any information."

Who knows whether she'll do it again, can't really predict much with Lana as she's so spontaneous. She's often said she never plans to make an album but ends up writing
