At Moogfest, the music revolution will be synthesized

JUDY WOODRUFF: The idea, how technology, music and science can inspire one another, and to the creation of distinct new sounds. Jeffrey Brown is back to take us to an unusual gathering held just a few days ago in Durham, North Carolina. JEFFREY BROWN: Start with a circuit board, add knobs and dials, solder everything together, and, eventually, if you know what you're doing, you have an instrument that can do this. Moogfest, named after inventor Robert Moog, is a celebration of the art, engineering and technology of synthesizers, machines that create sounds electronically. By night, it's a festival of different genres of music, centered on, as they call them here, synths.
