The 12-12-12 Sandy Relief Concert is set to be the largest event in music history ever recorded. Some of the biggest names in the music industry are now set to come together on Wednesday night, and via a host of live streams and social media help, the charity concert is expected to reach an extraordinary amount of people.

"Between TV, radio and online streaming on YouTube, Hulu, AOL, iHeartRadio and Time Inc brands, the concert will reach nearly 2 billion homes worldwide as the most widely distributed music event in history."

It will also be put up in select theaters in Hurricane-affected areas (several movie theaters in New York, New Jersey and Connecticut).

The concert for Sandy Relief is to benefit The Robin Hood Relief Fund which, the official page adds, “has launched a large-scale relief effort to aid our neighbors in the tri-state area whose lives have been shattered by Hurricane Sandy.”

“Now, one month out from the storm, thanks to our supporters, Robin Hood has been able to provide over $8 million in grants to more than 90 different groups.”
