I'm a new member but i use a lot this website since one year. I could start to suggest, as I have discover lot of krauty jazz rock band on this website like Embryo or Eiliff, to add the french band l'Éclair to the archives. They use Arp Odyssey and a strange king of electric piano. It sure it's interesting stuff for prog keyboardist like me. I dont know if its to put in jazz rock or krautrock and this is why it have to be on this prog archives. L'Éclair could be a good addition for those who like to listen to Embryo, Kornet, Cos, Karaba, Eiliff, Osibisa and Sunbirds. There a lot of progression in their music and have really good vintage keyboard solos and electric guitar solo. Like lots of prog rock or prog jazz band, it's a blend of lot of style.

And it's one of the popular underground bands of today that use prog melodies and fusion them with funk and muzak, but with krautrock hypnotism.
