Tomoya Ohtani on Sonic Lost World Original Soundtrack:

Island Relics

This is the image in which the parts like flute and electric piano, where the reverb, delay, and others started, play towards the depths while lightly repeating the minimal sequence such as percussion loop and marimba. It is a piece with relatively abstract atmosphere at the same time that there is plenty of clear music made of melody, sound, and others, but I render the moderate tension and the mood within the relics.
