I wanted to choose Baltang Ort, but it was unavailable in TIMJ. This video gives a good impression of the PTSD-inducing live show that left such an impression on me earlier in the year at the Barbican.
There are a few that are absolute masters of the genre. There's Aphex Twin, there's Amon Tobin, and there's Squarepusher. This is one of the best tracks I've heard from Tom Jenkinson in a long while. So good.
