British heavy metal legends SAXON are about to begin writing sessions for the follow-up to last year's acclaimed "Call To Arms" effort. The band's drummer, Nigel Glockler, writes on Facebook: "Working on getting the home studio tidy and then off next week for writing sessions for the next SAXON album…busy busy busy!"SAXON will release a new concert DVD, "Heavy Metal Thunder Live: Eagles Over Wacken", in early 2012. According to Classic Rock, it will feature performances from Germany's Wacken Open Air festival. "There are five in all, from 2002 to 2009," Byford told Classic Rock magazine. "But we've not got all five shows, in their entirety, because even I would get bored watching that! The most interesting one is 2009, which was Wacken's 20th anniversary and our 30th. We did a set that included songs from all of our studio albums, as voted for by the fans. And we did it with the most recent at the start working backwards to our debut album, 'Saxon', at the end." SAXON's new album, "Call To Arms", sold around 700 copies in the United States in its first week of release, according to Nielsen SoundScan. The CD debuted at No. 51 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. The digipack version of "Call To Arms" includes a glorious bonus — a free seven-track CD, "Live At Donington 1980".
