September brings with it the promise of something new. Specifically, something new from Iron Maiden, who'll release their first album in five long years.

With a career as lengthy and storied as theirs, that would seem increasingly difficult to do. But Iron Maiden will be releasing a first-ever double album, The Book of Souls. The 11-song project, recorded in Paris with longtime Maiden producer Kevin Shirley, was delayed slightly so that frontman Bruce Dickinson could deal with a since-cleared tumor diagnosis.

David Gilmour's first solo turn since essentially dissolving Pink Floyd after last year’s The Endless River is also on tap. The latest Scorpions studio album is finally getting a U.S. release, too.

Meanwhile, Keith Richards will be closing a gap of more than 20 years between solo efforts. The Rolling Stones guitarist previously issued two albums on his own, 1988's Talk Is Cheap and 1992's Main Offender. Don Henley hasn't been gone quite that long – "only" 15 years. His new project returns the longtime Eagles star to his country roots.

There are plenty of great live and reissue projects arriving, as well. Aerosmith's headlining set at the 2014 Download Festival will be released on DVD, Blu-ray and digital video. Then there's the Grateful Dead's 80-disc (yes, 80) box featuring various live performances during three decades with the late Jerry Garcia.
