Some of my favourites of electronic music at the moment:
Calvin Harris - that 'Acceptable In The 80's' song / video is stuck in my head...- has new album in June - has worked on one song for Kylie's new album.
MSTRKRFT - new (short) album 'The Looks' - if Daft Punk where Canadian. They've remixed Annie and Bloc Party in the past.
Rex The Dog - does killer electro/acid remixes and is working on his own album. Prototype is an awesome track.
Also Tiefschwarz, Tiga, Linus Loves & Vitalic (already mentioned)
Jean Michel Jarre has a new album out in March/April and going by the Youtube video its sounds likes he gone for a mainstream / commercial sounding dance record approach. Seems to be copying the artists he (may)once influenced...a little sad coming from a big fan
For techno yeah Kraftwerk's more recent albums would be a very good choice for a start...
outside of techno their early albums are magnificient
