About the artist

A long-time environmentalist who joined his wife Kim in co-founding Kōkua Hawaiʻi Foundation, a non-profit devoted to supporting environmental education, Jack has found immense purpose in caring for his community. This has included, most recently, working on and developing a learning farm. Jack is a long-term supporter of the Eden Project and Kōkua Hawaiʻi Foundation will be highlighted at the show with a call to action on the climate emergency in conjunction with Eden.

Jack’s decades-spanning career has included multiple awards and two Grammy nominations, more than 25 million album units sold worldwide, and countless sold-out tours, during which he has emerged as a leading force in greening the global touring industry.

Jack’s eighth studio album and first new full-length in five years, Meet The Moonlight, affirms him as an essential voice in elevating our perspective and subtly guiding us toward a more expansive state of mind.

In a departure from his past work, most of the album took shape from one-on-one collaboration with producer Blake Mills, an intimate and highly experimental process that involved embedding Jack’s elegantly stripped-back arrangements with enchanting sonic details.

Hollie Cook

Special guest: Hollie Cook

Hollie Cook is the queen of modern-day “lovers rock” — the lush girly harmony reggae style beloved in Britain since the 1970s. However, touring as a teenager with punk legends The Slits encouraged the fierceness within her sweetness. Hollie’s mentor was Ari Up, the band’s lead singer and a lifelong friend of Cook’s parents (Sex Pistols drummer Paul and her singer mother Jeni).

She has released four studio albums, beginning with her eponymous debut LP in 2011, as well as singles including Milk & Honey, Superstar and Postman. 

5x15 talks: Food Matters

  • Time: 5pm
  • Venue: Ground floor, Core Building
  • Admission: Free, no booking required

We're excited to be hosting a very special 5x15 event on food and the environment, to mark the Eden Project’s Food Matters campaign. Come to the Core before the Session starts to hear some fascinating speakers. 

The signature format of a 5x15 event sees 4 speakers each having 15 minutes to tell a relevant, entertaining and expert story. These events have been going for 12 years, featuring over 1,400 incredible speakers, including  Jeremy Irons, Emma Watson, Billie Eilish and David Gilmour. Check out their YouTube channel here.

The 'Food Matters' theme for this event ties in with Eden's programme that communicates the story of food, presents the challenges and solutions, takes a local and global view and provides visitors with hope, agency and tangible actions. Food is a great enabler of positive change for the planet and revolutionising the way we produce and consume food can help fix the planetary emergency.
