There are various bands like F.U.K.T (their drummer is a member here) around, but Nerve to me are unique in their ability to reproduce Jungle authentically, there is no other human who can play the genre and the old breaks with as much skill as Jojo.
I think Johnny Rabb has a band, and KJ Sawka does a solo DnB thing, but i think you'll understand what i mean when you compare their styles to Nerve.
EDIT: Raymond Bloom is the man to ask about this, shoot him a PM
