Collen will fly into London from New York next week to hook up with fellow band members Simon Laffy and Paul Cook.
And the trio will have two weeks to nail the bulk of the new record – the hotly anticipated follow-up to 2008’s Surreal.
“We’ve got most of the songs ready and we’re raring to go,” said Collen after the band signed a deal with Rocket Science Records.
“We’ve got two weeks to get the basic record done but we enjoy working to that kind of timescale.
“The first Man Raze album might have been a long time coming but we actually got it recorded in a few weeks.
“That’s the way this band works. It’s a bit different to Def Leppard. It’s a bit more old school.”
Collen is hoping the new Man Raze disc hits stores before Leppard hit the road for what is already looking like a busy comeback summer – after the band’s brief hiatus.
The Sheffield stars have been confirmed to headline Download on June 10 and the band will embark on a full US tour with fellow 80s chart busters Heart.
Man Raze, meanwhile, have recorded the title track for new racing movie I, Superbiker. The film is released next week and we’ll bring you a full interview with Collen then!
