For me: Hazard, Konichi and Decimal bass - But I think it's because these guys seem to producing in a very different style from the others (Hazard especially seems to have almost unattached himself from the jump-up genre)
Jump-up has always seemed a bit samey, or at least the stuff i've become Accustomed to has. However I do think it has it's place and mixes very nicely with a bit of tech. I just can't stand jump-up focused nights, I really don't feel like the attendants are there for anything more than MDMA and persistent rewinds and it just gets a bit silly.

This style of techy jump-up is what I'd personally like to hear more of. This track was dropped at last Critical night at Fabric and did not seem out of place for a moment.
