“No editing or other tricks, just 2 youtube videos played at the same time.”
In 2011, London-based Alessandro Grespan and his friends created a cool effect by playing two music videos at the same time, “New York, I Love You But You’re Bringing Me Down” by LCD Soundsystem and Miles Davis playing trumpet at Louis Malle’s Elevator To The Gallows recording session. By combining the two videos to play over each other, it makes it sound like the legendary Miles Davis is improvising on LCD Soundsystem’s song, thus creating an impossible (but fantastic) duet.
Try it yourself:
