Every great thing, balances at all times, at the razor edge of disaster," says Ken Kragen at the beginning of the trailer of the Hands Around the World Project, which launched on Earth Day. Kragen is the man who organised We Are the World—the '90s anthem, which was a coup of sorts with the presence of Michael Jackson and other legends, Lionel Richie, Stevie Wonder, Paul Simon, Kenny Rogers, James Ingram, Tina Turner, Billy Joel and Diana Ross. Now, Kragen and our own Oscar-winning composer AR Rahman, along with other notable musicians, visionaries and philanthropists, have joined hands for a global project titled, Hands Around The World. Also, a big part of the project will be Neil Morgan, an immersive entertainment entrepreneur, who is the brains behind a unique app that will use hologram and augmented reality technology to link one billion people holding hands around the world in a virtual reality selfie-chain for the benefit of climate change. This new project includes an anthemic song, and an album of songs showcasing different genres is also in the making. We spoke to Rahman, Kragen and Morgan about the project.
