Chozo Laboratory

Chozo LaboratorySamus Archives Sound Selection, alternatively titled Allarea BInternal files and Area 7Sound Test, is a theme in Metroid: Samus Returns. It was composed by Daisuke Matsuoka.
==Description==
It plays in most of Area 7, starting in the Chozo Tower, and is much more upbeat than the theme that originally played in this area in Metroid II: Return of Samus. This energetic theme contains various electronic sound effects, heavy beats, and a choir. It contains notes from Theme of Samus as well, most notably the female choir.
The theme was first heard in the Official Game Trailer for the game at E3 2017, but is also played in several other trailers including the SR388 Data File and the Samus is Back commercial. It is included on the Samus Archives Sound Selection soundtrack, a compilation of Metroid themes included with the Samus Returns Special and Legacy Editions.
The theme can be heard here.
==Trivia==
*Its internal name, Allarea B, seems to follow the same naming convention as Surface 1, which is internally named Allarea A. It is unknown how the two themes may have been related.
