The 'impossible' accelerating tempo changes in the Oppenheimer theme are not metric modulation — there is no clean mathematical derivation between tempos. Instead, Ludwig Göransson simply sent musicians the new tempo in their in-ear click track two bars before the change actually happened. Performers had to keep playing the current line, mentally switch onto the new click, and drop into the new tempo in real time. The eerie, 'floating' quality of the accelerations is the sound of elite musicians executing brutally hard production instructions that nobody would design on paper.
