I thought RAM was already on the downturn. They peaked with Discovery and Alive 2007 in my opinion.
I remember my mind was blown when i first heard #3 Television rules nation / Crescendolls, when it transition back to Television with a drop... absolute masterpiece of electro music
I suspect the reason is the duo simply wanting to do different things. After all, they've been Daft Punk for almost 3 decades.
To me RAM sounds like an Air album, not a Daft Punk album. I don't consider that a bad thing though.
