Re: Kraftwerk, Jean Michel Jarre and other electro artists!
I love Kraftwerk, and their drum programming has definitely influenced my playing, both in how I create drum parts and in improving my time-keeping.
About time-keeping, I'd tell you to just remember that most music out there is done to a click track, and practicing to any of this music can only help you. Kraftwerk is good for how precise and quantized everything is, but beyond that I don't see it as being a ton better for your time. Like I said, I think any music with drum programming will help you tighten things up.
Jean Michel Jarre, I'm not familiar with him, but I'll definitely have to check him out!
