I think the opposite. Without the interludes the album doesn't flow. The album would become one of these...
Track 1, end in silence
Track 2, end in silence
Track 3, end in silence and so on
With the interludes it would keep a low going on from song to song
Track one flows into Interlude which sets the mood for track two
Great example is take away The radiance between The Requiem and Burning in the skies.
Now without the Radiance the songs dont flow into each other
Get me?
