Essential Glastonbury is a promotional cover CD given away with issue 216 of Q magazine.

The CD was released in cooperation with Greenpeace with the result that the cover was printed on recycled paper.

A NOTE FROM GREENPEACE — Ancient forests are home to nearly two thirds of the world’s land-based species and are vital to the health of our planet.

The live version of "Block Rockin' Beats" was previously unreleased.
