Gravitational Wave observatories here on Earth are poised to end the "silent era" of Astronomy by measuring the vibrations in spacetime caused by colliding black holes and other energetic events. NASA and ESA are working together to open up the source-rich low frequency portion of the gravitational wave spectrum with the Laser Interferometer Space Antenna (LISA). A major challenge for this mission is how to deal with a data stream that is expected to contain the signals from tens of thousands of sources, including massive black hole binaries, stellar remant captures by galactic black holes, and a foreground of compact binaries in our own galaxy. Here we describe a fast and robust technique for simultaneously resolving tens of thousands of overlapping signals and recovering the source parameters. Our approach has been sucessfully tested on simulated LISA data, including the blind data sets of the Mock LISA Data Challenge.
