Came up with a blessed guess for RUSSOLO but had no way of figuring out AYOTOMETI whose various vowels need to be songs to a crossword constructor’s ears. Nice to see AYO TOMETI in there, and to make the acquaintance of RUSSOLO although his operate appears to have taken a pretty dark switch! Thanks for all these nice men on this website. On Jeff Chen’s site Will Nediger claims he does not concur with the cluing for 78A.
