What's in Your Head?

What's in Your Head? is the sixth album by the British heavy metal band Diamond Head, released on 30 July 2007 through Cargo Records. It is the second and last record they made with singer Nick Tart, who left in 2014 after moving to Brisbane, Australia made the distance too much to manage. It also marks the first appearance of guitarist Andy Abberley on a Diamond Head album.

Where its predecessor, All Will Be Revealed, was produced by drummer Karl Wilcox, this time the band brought in Dave Nicholls, whose earlier credits include work with Slipknot and Stone Sour. After its release the group concentrated mainly on touring, and a new full-length studio album did not arrive until 2016. That makes this a record from a quiet stretch in the band's story, and one worth hearing for the Tart-fronted line-up.
