Previously unreleased material by Britney Spears has been made available by one of the producers behind her 2007 album ‘Blackout’.

Danja – the professional name of Floyd Nathaniel Hills – produced seven tracks on Spear’s ‘Blackout’, including the singles ‘Gimme More’ and ‘Break The Ice’.

He also worked on album tracks from the LP ‘Circus’ and a trio of unreleased songs.

In a video posted on Youtube yesterday (February 22) by Danja the producer explains the background to two songs and shares a remix of ‘Blackout’ track ‘Hot As Ice’ (see video below).

Danja also speaks about his involvement with the pop star’s latest album ‘Britney Jean’. Discussing a beat he submitted for the album he states:

“It's uptempo and energetic. I thought we were going to do a ‘Blackout’ 2. You will see where I was going with it.”
