The City of Los Angeles, in collaboration with the L.A. River Day of Service, is presenting the Songs of the L.A. River Project. Local youth between the ages of 6 and 18 are invited to write and submit an original piece of music inspired by the Los Angeles River. The top two entries will win a chance to perform their song with Grammy-winning band Ozomatli at the L.A. River Day of Service on April 30. Submissions are due by April 15. E-mail a video or YouTube link of your performance to LARiverSongs@gmail.com. For more information, please go to lariversongs.posterous.com.
