Theres a Dean blunt live set video from years ago, a sort of boiler room type thing, when hype Williams played, i think, macba in Milan, and you can clearly see senni down the front, standing motionless, staring at Dean blunt with a sort of icy but not exactly malevolent look. He barely moves or averts his gaze the entire set.
I saw senni dj at a thing in Salford a few years ago and he was the best thing all night, just a really heavy layered set and it sounded amazing, very basic jacking/pneumatic and all around you.
It was in some large hangar warehouse type space and you could see very clearly from the crowd reactions that it was what people had been waiting for all night and really needed.
But then I listened to some bits of his albums, maybe something he did on death of rave, and they all felt very middling and instantly forgettable generic stuff.
