NEW YORK: Playing instruments made from naturally fallen trees, packaging albums with recycled materials and fueling tour buses with biodiesel are just some of the ways that North American bands are going green.

Illinois-based folk-rock band The Giving Tree Band says it will bring out what will be the world's first carbon-free album, Great Possessions in August.

"For us it's very meaningful to be able to keep nature healthy for future generations," said the band's co-founder, Eric Fink.
