A previously unheard portion of a soundboard recording of Led Zeppelin performing on January 18, 1975 in Minneapolis has been released as a bootleg.

Online posts and emails from bootleg distributors published this week show that four songs from this performance have been released as a non-label CD bootleg named “Wanton Song” after two snippets of the recording emerged online in February.

The tracklist for the soundboard portion of the release is below:

• The Song Remains The Same
• The Rain Song
• Kashmir
• The Wanton Song (cut)

The CD also includes three studio outtakes of Led Zeppelin recording The Wanton Song.

However, online forum posts have questioned whether this release actually contains any new material, or if it just packages the two snippets of audio which emerged in February with two previously released live tracks and the studio outtakes.

Sam Rapallo, the administrator of Led Zeppelin’s official forum, wrote online that he believes the source of this soundboard recording is around two hours long in total.

According to Rapallo, here’s the full tracklist of the source for this release:

• Rock And Roll
• Sick Again
• Over The Hills And Far Away
• When The Levee Breaks
• The Song Remains The Same
• The Rain Song
• Kashmir
• The Wanton Song (cut)

The first sample which emerged earlier this year features Robert Plant telling the crowd about Jimmy Page’s injury to his finger. “Jimmy had the misfortune to break one of his fingers … one of his fingertips,” he says, before the start of “The Song Remains The Same.”

The second sample includes Plant referencing “Kashmir,” which the band presumably just played, and then introducing “The Wanton Song.” The snippet ends midway through the song.

The entry for the performance on Led Zeppelin’s official website lists the following songs as having been included on the set list:

• Rock And Roll
• Sick Again
• Over The Hills And Far Away
• When the Levee Breaks
• The Song Remains The Same
• Rain Song
• Kashmir
• The Wanton Song
• No Quarter
• Trampled Underfoot
• Moby Dick
• In My Time Of Dying
• Stairway To Heaven
• Whole Lotta Love
• Black Dog
