I listened to a few of their big hits like 20th century boy and children of the revolution and I don't like that stuff so much it sounds like what I thought they sounded like (so I probably heard those two before and saw some tacky whistle test footage). But that "Electric Warrior" is great.
My CEO (he of the dub playlist fame) has done a Kraftwerk playlist today and I've recommended he check out Drexciya. So now I'm listening to Drexciya. This is the first thing that's come up on Spotify, basically, that's why I picked it. But it's real nice. I can't hear Drexciya WITHOUT imagining underwater worlds cos of their imagery/marketing, so this definitely sounds bubbly and aqueous with synths appearing out of the murk and flashing past like fucking silver fucking swordfish or whatever.
