Jason Mraz and Brett Dennen speak here about their contribution to an album for Survival International, the human rights organization for tribal peoples.
Bruce Parry, star of the BBC series Tribe and the forthcoming Amazon, has teamed up with some of the music worlds biggest names to create a fundraising album for Survival.
Musicians on the album also include KT Tunstall, Skin from Skunk Anansie, will.i.am (Black Eyed Peas), Johnny Borrell (Razorlight), Tom Baxter, Mystery Jets, Yusuf Islam, Hot Chip, the Go! Team and Mike Oldfield.
In addition, Guy Berryman from Coldplay, Jonas from MEW and Magne from A-ha have formed a new band specially for the CD called Apparatjik, and recorded a track that will also be used for the end credits of Amazon.
Every track on the album is exclusive, and has been written especially for the project.
The first section of songs is titled Amazon and features songs inspired by Bruce Parrys new series of that name, to be shown on BBC2 in September.
The second section of songs, entitled Tribe, is a collection of dance/experimental songs which all use samples of music Bruce recorded with the tribal people he lived with during the making of his hugely popular BBC show.
