Drowning Pool are in the midst of the "Sinner Unlucky 13th Anniversary" tour, revisiting their classic breakout album, so it's not surprising that Drowning Pool's late frontman Dave Williams is on their mind. Williams died of cardiomyopathy in 2002 while out on tour with the band during support of the Sinner album.

In remembrance of Williams, the band has issued a new video for the Sinner song "Soul" and launched a campaign that will both raise funds and bring awareness to treating heart disease.

In the "Soul" video, which can be seen above, both onstage and offstage footage of Williams and his Drowning Pool bandmates from back at the start of their career has been compiled to re-visit that era of their career.

The band says, "People assume drugs and alcohol are the cause when the news reports that a rock star has died. Dave actually died of the heart disease known as cardiomyopathy -- disease of the heart muscle. Dave didn't know he had it. It often goes undiagnosed. It affects people of all races and ages."

They add, "To celebrate Dave's life and contribution to music, we have partnered with the American Heart Association of Dallas, Texas and IndieGogo to raise both awareness of the disease and funds for further research and development of new treatments."

The band has set a financial goal for $13,000 for the newly launched campaign, which will run through April 18. Learn more about the campaign here.
