Well, I could definitely recommend the Orb since they just released and album with David Gilmour!

But for the best that modern electronic has to offer, here's a list of some of the best artists that use electronics and are very progressive musically:

Squarepusher
Aphex Twin
Amon Tobin
Luke Vibert
Mouse On Mars
Mike Paradinas
The Orb
Simon Begg

And while this group is not primarily electronic, they are heavily influenced by electronics.

And they are pretty fantastic!

Massive Attack.
