As Temple of the Dog inch closer to the release of their 25th anniversary deluxe reissue, they're letting fans in on more of the bonus material. The latest gem to surface is a demo of the previously unreleased track "Angel of Fire."

As you can hear, the track is a slow moving, swaying ballad that's guitar-led with Chris Cornell's soulful delivery. Check out the track in the video, which features some flickering flames throughout, in the player above.

In the lead up to the self-titled 25th anniversary release, Temple of the Dog have also released a demo of the track "Black Cat," which also didn't make the final cut for the initial album, as well as a remastered version of the disc's biggest single, "Hunger Strike."

The reissue will be available in a variety of formats, with the the largest package including four discs. The first disc is a remastered version of the original album along with alternate mixes of select tracks. The second disc has five demos including "Angel of Fire." The third disc is a DVD featuring promo videos and live performances, while the fourth disc contains Blu-Ray audio of the album with music videos. All of the packages will be available on Sept. 30. Feel free to peruse the packages and place the order for which you want at this location.

Meanwhile, the band, which includes members of Pearl Jam and Soundgarden, has a brief November tour planned. Dates in Philadelphia, New York, San Francisco, Los Angeles and Seattle have been sold out. A portion of each ticket sold ($1.50) will be donated to the Chris and Vicky Cornell Foundation that helps children in vulnerable situations.
