VOIVOD guitarist Denis "Piggy" D'Amour passed away Friday night (August 26) at approximately 11:45 p.m. due to complications from advanced colon cancer — so advanced that the disease had spread to his liver. D'Amour slipped into a coma Thursday night and died less than 24 hours later in the palliative care unit of a Montreal hospital, surrounded by family and friends. He was 45 years old.

Quebec City newspaper Le Soleil reported yesterday that D'Amour — who was diagnosed with colon cancer earlier in the summer — first entered the hospital for a routine operation, but several complications led his doctors to suspect more problems. Then the grim verdict was revealed: the cancer, already too advanced, was inoperable.

Only two months ago, D'Amour was in the studio working on the 14th album from the Canadian thrash-metal pioneers VOIVOD. More than two dozen tracks are believed to have been demoed for the CD, for which the group recently inked a deal with The End Records. However, the band were forced to put studio work on hold while bassist Jason Newsted (ex-METALLICA) was treated for tendonitis.

In a recent interview with Billboard.com, Newsted spoke about the material slated to appear on the group's next CD. "It's the most complete demos I've ever been involved in," he said. "[VOIVOD singer] Snake has already chosen his effects — exact timing of milliseconds for delay. We've had a long time to develop the demos, so there's about 23 or 25 songs that are absolutely listenable right now."

Newsted was a huge fan of VOIVOD before he was invited to join and he remains a great admirer to this day. "They created something a long, long time ago that may have been emulated many, many times since — but nobody can do it like the original," he offered.

Prior to his hospitalization, D'Amour laid down guitar tracks for a reunion CD from the legendary AUT'CHOSE, a '70s band from Montreal. That album is expected to surface next summer.
