If there's already a similar topic, my apologies.
For nu-jazz lovers there's no doubt that Japan is the home of famous nu-jazz and fusion music artists, for example Casiopea and Studio Apartment. These guys are geniuses when it comes to making and mixing their own beats instead of just sampling.
Here are some samples from my favorite artists, well some of them aren't exactly jazz but more of hip-hop/lounge fusion. If any of you also interested in this music genre, feel free to recommend me your favorites.
Best listened while relaxing on the couch drinking a cup of espresso and watching the sky on a starry night.
Casiopea
Studio Apartment
Daishi Dance
Nujabes
Uyama Hiroto
Jazztronik
Clazziquai >> They're actually Korean but what the hell, they're good.
Still got more, but this is enough I guess. Hope you enjoy.
