Bassist Jim Sheppard of Seattle metallers NEVERMORE will undergo surgery today (Wednesday, February 16) to remove a benign brain tumor. The band's vocalist, Warrel Dane, says, "Please, all metalhead brothers and sisters, send your positive energy for our brother."Sheppard in 2006 missed a number of NEVERMORE shows after undergoing a minor procedure for Crohn's Disease, a condition he's managed for nearly 20 years. Filling in for Sheppard was longtime friend James MacDonough (ex-MEGADETH, ICED EARTH). "The Obsidian Conspiracy", the new album from NEVERMORE, sold around 4,000 copies in the United States in its first week of release to debut at position No. 134 on The Billboard 200 chart. The CD landed at position No. 1 on the Top New Artist Albums (Heatseekers) chart, which lists the best-selling albums by new and developing artists, defined as those who have never appeared in the Top 100 of The Billboard 200.
