She says in the video link that she and whoever is going to be involved is going to go in there with no "planned" ideas whatsoever (obviously, if the others with her are "concerned" about how they are going to sound, those collaborators might spend some time sort of "planning" whatever they might play for the time).


Since Esperanza is sort of a fun person, I'm not sure how much Esperanza will "police" her collaborators about going into the 3 days with absolutely no planned musical ideas.


As far as having to "write" music - rock bands and funk bands are known to "create" music from "jamming." "Jamming" seems to be a mixture of previous musical ideas (their own or somebody else's), making mistakes to come up with "new" musical ideas, and whatever "creativity" can come from just playing together on a new moment in time.

So...

no jazz bands, funk band and rock bands don't have to "write" out anything previously to make new music.

Obviously jazz has the tradition of free-jazz where the creation mostly is supposed to be right then and there when the jazz musicians are playing (but obviously many have said free jazz and jazz improvisation in general can be "grounded" in musical statements that the musicians are inclined to repeat - even if they try to "change" those often repeated music statements here and there when making free-jazz or improvising in general).

So, no Esperanza and her collaborators for those 3 days don't have to write out what they are going to do that day.


The question is: "will it be any good if done this way?"

That will be based on how much Esperanza and the musicians "plan" or "write" while in the situation those 3 days. Esperanza could do what Miles Davis said he did in the "Bitches Brew" sessions, which is write out or just verbalize a few musical ideas and instructions with some kind of direction to it ("play it crazy", "play it 'off-kilter'", "play it sloppy", etc.) and just let the musicians "jam" on those brief ideas for a while.

Esperanza said that she and the musicians will be checking the feedback they get from those watching the live-stream, so if people write in that the music should go off in a different direction or feeling, perhaps Esperanza and the musicians will take those cues from the audience and adjust what music they start to come up with in the remaining time they have in the 3 days.

Esperanza did say that they would be taking breaks to rest and probably evaluate and adjust what they are doing and, of course, read the feedback that she and the musicians are getting from the audience.


This project is sort of like Esperanza saying that she and the musicians are so good at writing songs and jazz improvisation and "being creative" in general, that she and the musicians can do something in the space of 3 straight days (without planning) that can show something about how creativity works and develops.
