“Deus Ex Machina,” the upcoming Empress Valley soundboard bootleg of Led Zeppelin’s March 21, 1975 Seattle show, is now expected to be released in mid-June, according to someone with knowledge of the Japanese bootleg industry.

It had previously been rumoured that “Deus Ex Machina” would be released at some point in May, then last month that release date slipped back to either late May or early June.

Empress Valley has also detailed the different formats that its new release will be made available in:

• An “Ultimate Collectors Edition” box set that will include the March 17, 1975 and March 21, 1975 shows across seven CDs. This will be limited to 100 copies.
• A limited edition, 14-CD box set that includes the March 17, 1975 and March 21, 1975 shows and audience recordings of both nights to go with the soundboard releases.
• Another box set, this time across eight CDs that will include the new soundboard release of March 21, 1975 alongside an audience recording of the show.

“Heartbreaker” was the first track from the upcoming bootleg to be published online. Led Zeppelin bootleg website Starship posted “Heartbreaker” online, and you can hear it at this link. Click the speaker icon to download the track.
