Guitarist Kirk Windstein has announced his departure from Down in order to fully focus on working with Crowbar. Windstein revealed his decision through Facebook, saying, "For months now, I have been posting that I am concentrating on Crowbar 100 percent full time," he kicked off (via Blabbermouth). "2014 marks the 25th anniversary of Crowbar and it's a great feeling to put my heart and soul into something that I created so long ago." Kirk concluded by discussing the new album plans, "We are entering the studio on December 16 to record our 10th full-length record. Look for a late spring release on eOne. See y'all on the road with Crowbar!" Windstein is replaced in Down by the group's longtime stage manager Bobby Landgraf, who addressed Kirk's departure in a separate post. "Feeling very lucky to have this gig with Down. It wouldn't be the same without Kirk Windstein's blessing. He is Riff Lord and the new Crowbar will be amazing." Meanwhile, Crowbar have announced Jeff Golden as their new bassist and a replacement for Patrick Bruders who abruptly quit the band earlier last month. "I'm more hurt than anyone about Pat leaving Crowbar, but keep in mind that there were years that I was the only member in Crowbar," Windstein stated. As for Down, Phil Anselmo and co. are currently busy in the studio working on a new EP release. The latest Crowbar studio effort, "Sever the Wicked Hand," dropped in February 2011 through E1 Music.
