BAUGLIR: In German, I believe we will find him, if we lose a revolutionary leader, grasp the way and spin.
IRMO: Dwarf gains a thousand for him, despite the turmoil.
G: Fair disgruntled, she is, and a little discombobulated too!
NAMO: Well may you do this, in great perturbation, in his halls.
O: A confused astronomer will lead you to him.
INCANUS: See him where a muddled murderer meets a burning sphere returning.
SULIMO: Note fea in great trouble for him.
ELBERETH: An evil look meets a little woman. She shakes it up.
SARUMAN: For him, a ford and an eighties singer each lose direction, and meet.
The singer is Gary NUMAN, very big in the 80s and known for using lots of electronic sounds. I did think of mentioning that he and SARN lose the *same* direction. But it flowed better without.
It IS 'BIG NOISES,' but not because of the Music of the Ainur, (I didn't think of that). It's simply because a 'big noise' is slang for a person with a lot of power/authority/influence.
P.S. It WAS a vowel you needed, as it happens, but you forgot the consonant clusters BR and BL!
This is the Gary Numan song I remember most clearly:
