Vocal sensation Mariah Carey has finally unveiled the official music video for 'Almost Home', which features on the 'Oz The Great and Powerful' soundtrack.

She premiered the song last month, but the accompanying visuals have now been released to coincide with today's (March 8) cinematic release of the aforementioned Disney movie.

The video, which she revealed was directly by David LaChapelle, begins in black and white and shows Carey singing along to the track while footage of the film is spliced in, but it soon changes partly to full colour as more dramatic scenes from the motion picture are included.

Speaking about collaborating with Disney for the soundtrack, she tweeted: "I've always loved Disney + am very happy to collaborate on this project with them."
