Swedish metal veterans Candlemass revealed Friday they have parted ways with Robert Lowe, who handled the lead vocal duties on the band's last three albums.  Lowe will be replaced during upcoming live Candlemass shows by former Yngwie Malmsteeen and Adagio frontman Mats Leven, who has reportedly been close to the band for years.  Candlemass is preparing, meanwhile, for the release of "Psalms for the Dead," which has been billed as the 11th and final record from the band.  The record hits stores June 8th.
