I like progress......sive rock. Why do so many gasp in awe as artists move on for one reason or another and follow different paths. They feel institutional bands should remain the same and give us the old stuff, brilliantly.
I have to say I am NOT a fan of Trevor Horn. Not because he isn't talented or an accomplished musician. He has, on a few occasions, taken to stage for his work. But he's a producer, and a successful one at that. But he is known as a POP producer. Wiki introduces him thusly:
Trevor Charles Horn CBE (born 15 July 1949)
[1] is an English pop music
record producer, songwriter, musician and singer.
The one thing I fear in the upcoming album is the overinfluce of Horn and Rabin's POP oriented tastes.
I do look forward to Benoit contributing a new level of a symponic prog nature, but like that of Mystery, where he fared very well. Their album, especially One Among the Living. He was exceptional. I did see Benoit with Yes, twice. He was a little rough - it was in the early dates of the tour. But he carried it off. He did not fail. The songs were intact and did not fall apart. One Among the Living was one of the best albums last year, especially the incredible epid Through Different Eyes. Look for something like that to come.
Personally, making suppositions on the album prior to the actual release is a time waste. Everything you "suppose" closes you mind a little more each time so you won't be properly open to the new.
So, there's my humble opining. Let them do what they feel they want to do. But that's just MHO
