A real mixture of female voices:
Annie Lennox, Lisa Hannigan, Laura Viers, Patti Smith, Elle King, Evanescence, Madonna, Lady Gaga, Agnetha Faltskog and others...
...with Mozarts requiem and White Noise - An Electric Storm...thrown in the midst for good measure
just played whatever the current track made me think of next - uncertain how the White Noise track The Visitations came into mind.....
