The Doors‘ complete and original recordings of 1967’s Live at The Matrix, will be released on September 8.

It will be sold as a limited-edition 5-LP and 3-CD set and will include two, never-before-heard recordings of “All Blues” and “Bag’s Grove.”

Although bootlegs of the five different club shows have circulated for years, these are the actual first-generation recordings, from the first-generation 7″ reels.

The boxset titled, Live At The Matrix 1967: Original Masters, was recorded at The Matrix, a San Francisco pizza parlor-turned nightclub.
