the Advent live is a bit of a one man kickdown to say the least! (although it is just Cisco moving behind a laptop and some drum machines- albeit in a very funky way) and some of his stuff (esp the newer singles) sound quite fresh to me.
Cari Lekebusch I still consider to be a pioneer, has a very trippy feel to his groove. Same with Chris McCormack- surely some of his output has to be considered innovative.
