Below is “Madrigals of the Rose Angel”, a 14-minute ‘mystical twilight’ ambience (with vocal). Budd put it together for his 1978 second album Pavilion of Dreams, produced by Brian Eno. (The pair collaborated on two very good albums in the 1980s.)
P.S. If you’re feeling adventurous, you might take a look at The Quietus 2013 Albums of the Year (annotated list of 100). Somehow I’ve heard of 10 or 20 of these names – but we need such filters more than ever in these times of Bubble-gum Grammies and non-stop twerking diverting us from things we might actually want to remember.
