Moroccan producer saib. is my new best friend. I have been on a Cowboy Bebop OST kick all day, and so to hear "Adieu" transformed so breezily is heartwarming.
For the uninitiated, "Serenade" samples a tune played at the beginning of Bebop's two-part series finale. It's a beautiful song in its own right, and saib. treats the original material with the care of a true fan. See you on Bandcamp if you want to hear more saib. goodness, space cowboy.
