Patagonia has teamed up with a group of musicians to create Patagonia Music. Artists donate exclusive versions of songs—Patagonia says you won't find these songs anywhere else—to the Patagonia Music Collective. When a listener purchases one of the songs on iTunes, a portion of the sales goes to an environmental group.
Some of the musicians so far are Ziggy Marley, Phillip Glass, Pearl Jam, Maroon 5, and Brett Dennen.
You can preview some of the tracks in the Patagonia music player.
