Trapped In Amber
From Halopedia, the Halo wiki
Trapped In Amber is the seventh track included in the second disc of the Halo 2 Anniversary Original Soundtrack. It is the remastered version of In Amber Clad from the Halo 2: Original Soundtrack, albeit longer by about a minute. The reason for this is because in the original Halo 2, the track loops many times, and vocals are featured in every second loop. The title references the way objects can be fossilized inside tree resin (amber), especially insects that are perceived to be eternally trapped and kept pristine within their amber prison, as was popularized by imagery in the 1993 film Jurassic Park, as well as the name of the Halo 2 ship UNSC In Amber Clad.
