I feel ya man. Some of my most respected producers play the most random sets.
Ive seen spectrasoul twice, both times were a bit of a let down. Jubei was really quite boring too.
I s'pose its to be expected though, these people take all their time making sick tunes and promoting as best they can, not necessarily honing their dj skills. The amount of travel these guys put it im suprised they even get a chance to do that!
If anything I enjoy the unknown DJ's more because their only agenda is to play music they love, not loads of random dubplates in no specific order.
