Live music in three arenas, old school activities like hopscotch and four square, and a live mural installation by artist Slang are among myriad activities planned for this year's Sound System Block Party.

Presented by Wicker Park retailer The Silver Room, with support from donations and a community grant, the block party is scheduled for 11 a.m. to 10 p.m. Saturday at the corner of Evergreen and Milwaukee Avenues, near Hollywood Cleaners.
