Armstrong's 'Mechanical Man"

Green Day’s Billie Joe Armstrong hasn’t been resting on his laurels, despite picking up a Grammy for record of the year (Boulevard of Broken Dreams). His latest project has been lending his voice to the Charles Manson puppet in the upcoming "Live Freaky! Die Freaky!" movie.

The Green Day frontman has also recorded his first solo effort, entitled “Mechanical Man,” for the movie’s soundtrack. Fans of the popular pop-punk group will find Armstrong’s song to be a departure from the norm. The track has been described as a “horn- and electro-laden whimsical pop number.”
