I revisited some interviews from Honeymoon release time and found some interesting info, so there is a recap:
— Lana had 17 compositions she had been working on for the album, it is 14 released tracks + California, Crazy for You and Say Yes to Heaven (the strongest u released that were considered); or 13 released tracks (minus cover) + California, Crazy for You, Say Yes to Heaven and Paradise (as the rest are rough)
— In one interview she said she had already started recording for the next long play during mixing of Ultraviolence, however, in the other one she said she started sessions in September 2014 (which is common knowledge)
— What is interesting, she the first and only time mentioned the sound of the early version of Ultraviolence (that she done with Rick before handing it over to Dan), saying that first sessions for Honeymoon sounded very similar to the easley version of Ultraviolence
I think interesting is that she mentions and acknowledges the early Ultraviolence with Rick, specifying “Early sessions for Honeymoon sounded familiar to the early version of Ultraviolence” which is for sure the common sense, but it was just random she acknowledged that!
