Feb. 23 (UPI) -- Music producer Danja on Saturday released three previously unheard Britney Spears demos from her three most recent studio albums.
In a video posted on YouTube, Danja finally made good on his promise to make available previously unheard material, Digitial Spy reported.
The first demo was intended for Spears' 2008 album "Circus." Danja said the song came about after his experimentation with a more rock vibe for the album, which "didn't work well."
The second track was intended for the "Britney Jean" album."So I said I'll go all the way over. More than anything, [Spears] nailed the energy and vibe that I wanted to capture on the track," he said.
The third track was a remix of "Blackout" track "Hot as Ice.""It's uptempo and energetic. I thought we were going to do a Blackout 2. You will see where I was going with it," he said of the track.
