Each summer KISW combines some of the biggest names in rock with up and coming artists for a full day of live music at White River Amphitheater. Over the years fans have seen everyone from Alice in Chains to Avenged Sevenfold, Slipknot to Shinedown. In 2005 KISW teamed up with Pearl Jam’s Vitalogy Foundation to raise money for Seattle charitable organizations. $2 from each Pain in the Grass ticket is donated. Over the years, fans have helped raise over $76,000.
