My new top 5 is:
Underworld
New Order
Kraftwerk
Alex Smoke
Circulation
isn't New Order more of a band though? i'm not referring to their earlier days either. they definitely played with instruments live right?. (i think that playing solo-produced electronic music with a band is a neat approach though.)
regardless, i still love them to death, but when i think producers, i imagine guys with computers and hardware.
(New Order?)
(Cut Copy) if New Order counts, i feel like they do too
(M83) same
Flying Lotus
Amon Tobin
Avalanches
Flying Lotus
Amon Tobin
Bonobo
Daft Punk (admittedly i've never been able to listen to an entire DP album without getting bored, but they deserve to be on here just because "One More Time" is easily one of the greatest songs ever recorded)
