Into the Wild is the debut solo studio album by Pearl Jam vocalist Eddie Vedder, and is based on his contributions to the soundtrack for the film of the same name.

[2] Vedder said that Penn "gave [him] a lot of freedom," and added that "the biggest thing was trust, which was just kind of unspoken.

Thom Jurek of Allmusic called the soundtrack a "collection of folksy, rootsy tunes where rock & roll makes fleeting appearances.

"[1] Vedder's cover of the song "Hard Sun" (originally written by Toronto-based singer-songwriter Gordon Peterson under his stage name Indio) features backing vocals by Corin Tucker of Sleater-Kinney.

[7] Since its release, Into the Wild has sold 369,000 copies in the United States, according to Nielsen SoundScan,[8] and has been certified Platinum in Italy[9] and Gold in Switzerland.

[11][12] Vedder continued the tour with a second leg in August 2008 composed of fourteen dates focusing on the East Coast and Canada.

[14] Rolling Stone staff writer David Fricke gave Into the Wild three and a half out of five stars, saying that Vedder "[tosses] his weighty baritone onto earthy, folky tracks that temper the romance of absolute freedom with an eerie foreboding.

He said, "The handful of somber, droning mood pieces don't really transcend their film-contingent origins, but on the actual full-length songs...Vedder's incantatory vocals and campfire instrumentation evoke the eerie beauty of untouched land.

He said, "Eddie here answers what you might be inclined to describe as the call of the wild with a series of mostly handsome, jangly folk-rock ballads.

In the review, Fullerton states that "due to Vedder's interest in all things anti-corporate, McCandless' renouncement of materialism is celebrated rather than the fact that he eventually died."

"[17] AllMusic staff writer Thom Jurek gave the album two and a half out of five stars, saying that "musically there isn't enough imagination to distinguish [the songs], to set the tension of dynamic in motion.

[21] At the 2008 Grammy Awards, "Guaranteed" received a nomination for Best Song Written for a Motion Picture, Television or Other Visual Media.

[22] "Guaranteed" was also nominated for a 2008 World Soundtrack Award in the category of Best Original Song Written Directly for a Film.
