"Deep Time" is the thirteenth track on Boards of Canada's fifth studio album, Inferno. It was originally released on April 16th, 2026, as the video "Tape 05", without further information.
The title of the track may refer to the concept that shares the same name. The concept of "deep time", first developed in the 18th century, is geological time that spans billions of years and provides temporal framework for the Earth's formation and evolution, the development of life, and the slow processes that shape planetary change.
Another reference to Deep Time could be the volume published in 1999 by the astrophysicist and science-fiction writer Gregory Benford. In the volume "Deep Time: How Humanity Communicates Across Millennia"[1], he confronts our growing influence on events hundreds of thousands of years into the future and explores the possible "messages" we may transmit to our distant descendants in the language of the planet itself, from nuclear waste to global warming to the extinction of species.
Intentional or not, Deep Time is the 13th track from Inferno, meanwhile the gap between the album and Tomorrow’s Harvest is 13 years, and Deep Time was the first track from the album to be revealed.
Samples / Lyrics
0:31 onward, a wind-like noise can be heard for the rest of the track.
Near the end the of the track, samples of what could be highly obfuscated voices or seagull calls can be heard.
Trivia
"Tape 05" was originally speculated to be "Father And Son", due to it being the fifth track on the album and similar in length to the video.[2] This later turned out to be false, as it was confirmed to be "Deep Time" instead after the Inferno listening parties.
The note that occurs at 3:00 is not present in the "Tape 05" version of the track.
On May 27th 2026 two days before the release of Inferno, the White House posted a 15-second clip to X, imitating the VHS style of the "Tape 05" video promoting the Trump administration, which used a sample of "Deep Time" without any permission, the post was immediately met with heavy backlash from fans, in a statement sent to Resident Advisor, Warp Records in response said that nether the label nor Boards of Canada "condone the unauthorised use of their music for political messaging".
