Rise Against played a private show at Skatelab in Simi Valley, CA on Monday (10/1) to celebrate the birthdays of music journalist Trevor Kelly and Last of the Believers/Spark of Life member Spark of Life, and as No Echo points out, tons of exciting guests showed up to do classic hardcore covers with Rise Against. Moby joined for Minor Threat's "In My Eyes"; members of Youth of Today, Death By Stereo and Texas Is The Reason joined for Youth of Today's "Break Down The Walls"; Touche Amore frontman Jeremy Bolm joined for Minor Threat's "Minor Threat"; Strife guitarist Andrew Kline joined for Black Flag's "Nervous Breakdown"; and Zoli from Ignite did Misfits' "Astro Zombies." You can watch videos of all of those and see a few more pics below.
