Seattle metallers NEVERMORE have tapped Dagna Barrera to play bass on the band's current "Power Of Metal" European tour with SYMPHONY X, PSYCHOTIC WALTZ , MERCENARY and THAUROROD.Regular NEVERMORE bassist Jim Sheppard underwent surgery on February 16 to remove a benign brain tumor and is said to be on his way to a full recovery. Dagna previously played bass in NEVERMORE singer Warrel Dane's solo project and is also a member of the Seattle-based progressive rock band ONE UNDONE. Fan-filmed video footage of NEVERMORE's February 28, 2011 performance at l'Elysée Montmatre in Paris, France can be viewed below. 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.
