This is probably the most common harmonic mixing transition – corresponding to one counter-clockwise rotation on the circle of fifths. In this case, the first track is in Bb minor phrygian, and the second track is Eb minor phrygian. So the root key has shifted up by 5 semitones. I call this a parallel interval because, due to the modes being the same, all notes are transposed an equal amount. Most harmonic mixing tools don’t actually differentiate between the different minor/major modes (instead only detecting major or minor and the root), so a parallel interval is a bit more specific. The transition starts at 6:10.
