(Prog) Glass Hammer will release 16th studio album Valkyrie in the autumn, they've confirmed. And they've told Prog that vocalist Susie Bogdanowicz has moved up to front the band, with support from mainmen Fred Schendel and Steve Babb.

She replaces Jon Davison, whose role has diminished since joining Yes in 2012. The follow-up to last year's The Breaking Of The World is describe as a full-blown concept album in the tradition of 2002's Lex Rex and 2005's The Inconsolable Secret. In a video trailer, Glass Hammer tease the line: "The battle was only the beginning. This war was going to last� for ever."

Babb tells Prog: "Our fans have been begging for Susie to have a bigger role in our music for years. We're happy that she'll be fronting the band, with Fred and I in supporting roles.

"So the role of vocalist in Glass Hammer stays within the original core group. Of course, Kamran Alan Shikoh and Aaron Raulston remain solid members." Read more here.
