After months of rumors, actor William Shatner has confirmed the news of his concept album that includes contributions from some of music's most iconic metal and rock musicians. 'Searching for Major Tom' is set to hit stores next month, and features the likes of guitar great Zakk Wylde and Alice in Chains bassist Mike Inez, among others.

"It’s staggering because half of them, so I’m told, sought us out, and the other half jumped at the chance," Shatner tells Metal Hammer. "So we have twenty of some of the greatest musicians alive. The accumulation of talent on this album is phenomenal. I’m bowled over!"

The album's character, Major Tom, was inspired by the character of the same name from David Bowie's 1969 single 'Space Oddity.' Naturally, Shatner covers the tune on the album, among other classic hits such as Black Sabbath's 'Iron Man,' Queen's 'Bohemian Rhapsody' and Elton John's 'Rocket Man.'

"As I began to listen with enthusiasm to rock ‘n’ roll, this sound called ‘heavy metal’ began to intrude, and the thought was, 'This is the next level of dissent,'" says Shatner. "Now, having done some of the heavy metal songs, I realize what it’s all about, which is the energy, the passion, and I’m slowly evolving my musical taste, as a result of the work I’m doing."

Shatner was in awe of the musicianship and caliber of artistic talent taking place throughout the making of 'Searching for Major Tom.'

"A lot of these artists [on the album] just laid it down on the track and sent it in," notes Shatner. "In Zakk Wylde’s case, I was there, and I watched a virtuoso musician, and how he works. I’d laid down my vocal with [producer] Adam Hamilton in his studio prior to Zakk, then we went up to Zakk and heard what he was doing. I realised that what I had done was totally inadequate. I did my bit, but it didn’t have any deep understanding of what he was going to do. So after his vocal, I had to go back to the studio and lay down the track again!"

'Searching for Major Tom' is set to hit stores on Oct. 11.
