The In B Flat project "is a collaborative music and spoken word project conceived by Darren Solomon from Science for Girls.
The videos can be played simultaneously -- the soundtracks will work together, and the mix can be adjusted with the individual volume sliders.
Videos have been selected from many awesome submissions from many awesome people."
I used a combination of bass, guitar, vibes, kaoss pad, keyboard, trumpet, clarinet, singing, and spoken word.
You can find all of the audio samples at http://www.inbflat.net/
I hope you enjoy!
Please contact me if you would like to use this in a project. We can discuss the details.
