In Bb - a collaborative music/spoken word project

Composer and producer Darren Solomon has created this lovely interactive video piece, consisting of a grid of twenty videos of music or spoken word, all in Bb. Founded on the realization that multiple embedded YouTube videos can be played simultaneously, this site lets you create a piece by starting the videos at different times and playing them at different volumes.

Sun Boxes:

Sun Boxes are an environment to enter and exit.  It’s comprised of twenty speakers operating independently each powered by solar panels.  There is a different guitar sample in each box all playing together making the composition.  The guitar samples are all of different lengths so the whole piece keeps evolving.
