OK . . . so the above video appears to have the 2 tracks on the B side of the 12-Inch vinyl Record titled Anima (Preview Limited Edition).
According to the Notes section of the discogs.com page for Anima (Preview Limited Edition): Given to attendees at the Los Angeles IMAX premiere of the ANIMA short film by Thom Yorke and Paul Thomas Anderson on June 21, 2019. Also given on select European and North American IMAX screenings on June 26, 2019. The Alternate Mix of Dawn Chorus is the synth only mix from the movie
That last sentence does not make sense to me. It says "the synth only mix from the movie". I just watched the Anima short film that's posted in this thread. To me, the version of Dawn Chorus in the Anima short film sounds like the version from the Anima album. Thom has vocals during Dawn Chorus in both the short film and the album. Neither is "synth only".
If the Alternate Mix of Dawn Chorus is synth only . . . . then maybe it's only on the A side of the 12-Inch Vinyl Record titled Anima (Preview Limited Edition). Does anyone else have a different interpretation?
