The record is available now for $9.99 and features recordings of tracks performed at the two-day Pathway To Paris concert held last December in the French capital.
Tracks on the LP include "Bloom" by Yorke (which recently appeared on his BBC Radio 1 Bedtime Mix), plus "People Have The Power" and "Wing" by Smith. Flea and Warren Ellis collaborate on "Two Suits".
Pathway To Paris was run to coincide with the UN Climate Change Conference, and aimed to inspire action about climate change.
