In all the furore about Steve Harris’ solo album British Lion, it’s easy to forget he’s not the only member of Iron Maiden to have dabbled in side-projects.

True, it’s been a while since Bruce Dickinson did anything – although Harris doesn’t think it will be long until he does – but Adrian Smith hasn’t stood still during the rare downtime Maiden manage to scrape together.

Check out the video below for Tortured Tone, the single from his Primal Rock Rebellion album.

Smith teamed up with former SikTh frontman Mikee Goodman on the project, which the guitarist describes as a 50-50 collaboration. But he’s not sure if there’s more to come from the duo since Goodman shot the band’s videos and the experience set him off in a new creative direction.
