Jack Nitzsche's Exotica Music in Indian Runner

Nitzsche's music for "The Indian Runner" (1991) includes an Exotica instrumental when Frank is swimming to his bride. What is the name of this piece? Is it a Nitzsche recording or another artist? It is not listed in the credits nor is it listed anywhere online. No music ID app can identify it. It is not on the soundtrack album. I believe it is unreleased.

I searched all the topics and found nothing.
