DOWNTOWN LOS ANGELES ( — It’s almost time for “Light Up the Blues,” a concert held Saturday night that benefits Autism Speaks.

The concert is hosted by Kristen and Stephen Stills of the band Crosby, Stills and Nash. They have a son with autism who has become a highly-talented filmmaker.

Chris Stills says his brother is his main inspiration and why he became a producer of the concert. Chris and his father, along with many others, will be part of this family affair.

Jack Black is the emcee for the annual event’s third year in raising awareness and money for the cause.

Also joining the jam will be talented artists with autism, such as Nick Guzman.
