Well, Bangalter can write, but takes some of early Electro-funk from the 70's and breathes new life into it... He's really great!
I love how he's pretty much created the French House scene too. He's influenced a nice little record studio here in Canada called Eyezcream Recordings... Ever heard of Dave Armstrong? Make Your Move? Remixed by some of the greats (Clamaran, Basoski). Huge here in Canada.
Don't forget about Daft Punk's new album coming out soon too!
