From the sets i've seen on be@tv, i would recommend for different times/purposes:
Zabiela + Sasha at Shelborne (even though a huge part of it is almost muted)
Steve Lawler (Viva Music/Shelborne)
David Squillace & Matthias Tanzmann (Circo loco)
Solomun at Shelborne
Heidi at Shelborne
I'm sure i missed some, but these are the ones that have stuck in my head after listening to the first time.
