On the Decks EFX and 909 CD, the booklet has a graph inside showing which tunes are playing at which point in the mix (bit geeky perhaps, but hey!) On the graph there are very often two, or even three tunes playing simultaneously. This was publicised as a live mix. If Hawtin can play three tracks at the same time, whilst using the FX machine and the 909, then I don't really see how you can claim he can't mix. For me, his mixing ability is much more obvious in his minimal/dubby sets, so maybe you should listen to one of those?? The bouncier, clubbier sets are still good, but not as skilled in my opinion, so don't reflect him as a DJ. You might think he is too linear and straightforward in his mixing, but he is undeniably skilled and capable, perhaps just that his mixing style doesn't suit you?
