In what’s seems to be the next piece in the intricately epic prog-puzzle, Tool have shared 4 minutes of a new track named ‘Descending’. The band played the track live in 2015, which guitarist later on Adam Jones said would be part of a new album, also noting that the 4-minutes played was only a portion of the track.

The track has now been used as part of a trailer posted to the band’s Facebook page to promote their upcoming music clinics. The version used seems to be a live recorded version, which one Redditor has picked up may have “been a soundboard recording of the soundcheck/VIP event they did previously.”

Last week Maynard took to Lars Ulrich’s Beats 1 show, giving fans further insight into what the recording process for the new album is currently looking like.

The frontman blamed “timing issues” on the current prolonged recording process, saying “there’s a lot of timing issues with Tool getting to the studio, I always kind of gauge where they’re at, and try to figure out where things are going.”

He also took to Twitter last week to say, “My work is done. Words, melodies. Waiting on them to track. Then I can finish. Can’t track to music that isn’t recorded.” He’s since deleted the tweet, which has since let fans speculating even further as to where the band may be up to with the new album.
