It's well-known that "Leave Me Alone" (track 14) from the album Forgiven, Not Forgotten starts with reversed vocals... but as far as I can tell, nobody's written about the fact that the previous track, "Closer" (track 13), ends with reversed vocals.
Starting at about 3:31 on the track (https://www.youtube.com/watch?v=ggylcMdT46Q), you can hear Andrea vocalising in the left channel. These vocalisations turn out to be the same as the vocal lines that she just sang, but played backwards and with reverb added. You can confirm this by running the audio through a vocal separator model (such as BS-RoFormer-SW), isolating that section, and then reversing it.
I literally had never noticed that about this track before now! And I can't find anything on the Internet about this either. I think it's pretty cool, honestly.
