Footage of leading bands playing at the annual Eden Sessions will be launched for free on YouTube.
Videos shot at the eco attraction near St Austell over the past 11 years will be released onto a dedicated YouTube channel on a monthly basis.
The first batch on the channel, called Eden Sessions TV, includes tracks from Plan B, who played last year, and Jack Johnson, who played a sell-out show at the venue in 2010.
Also featured will be the 2011 performance of The Flaming Lips and Australian musical comic Tim Minchin, who headlined last year.
As well as live performances, Eden Sessions TV will carry features and interviews.
The first month will see Sir Tim Smit, Eden's chief executive discussing modern urban Britain with Plan B and environmental issues with Jack Johnson.
Sir Tim said: "In the past 11 years we have witnessed some truly memorable nights at the Eden Sessions.
"So many wonderful artists have performed to their absolute best inside the greatest live arena in the world.
"I'm proud to be able to launch this new channel which will share the highlights of the Eden Sessions.
"We are letting the whole world into our secret."
Jack Johnson said: "The Eden Project is one of those rare music venues. It's a special place where the surroundings are so powerful they become an active part of the show."
Patrick Walker, senior director of YouTube Music, said: "The Eden Sessions have become a hallmark of the British music scene and have hosted some fantastic performances."
