Led Zeppelin have unveiled a previously unreleased version of their 1979 track “In the Evening.” The early take of the tune features decidedly less production, as the instruments and vocals lack many of the effects that appeared on the original album version.

Led Zeppelin’s long-running reissue series will come to an end on July 31, when the band releases deluxe versions of 1976’s Presence, 1979’s In Through the Out Door and 1982’s Coda. Like the previous reissues, each album will be accompanied by a companion disc of alternate versions of different tunes from the LP.
