ASCENSEUR POUR L’ÉCHAUFAUD is a masterpiece, and one can only speculate what more Davis could have done in the film music realm. Also love its use in Lee Chang-dong’s BURNING (2018).
arte will broadcast it tomorrow evening and it is already available online for those who can access it:

If I am not mistaken there is as least one more Miles Davis score, his collaboration on DINGO with Michel Legrand:
