It hasn't quite been 10,000 days since Tool's last record, but the wait could soon be over.
Singer Maynard James Keenan says the prog-metal band is about to enter the studio to record the long-awaited follow-up to 2006's 10,000 Days.
"Started getting music files from the boys w the word FINAL in the title a few months ago after 11 years of begging," he wrote on Twitter.
"That in theory means the tracks won't change out from under me while I'm trying to write stories and melodies to them. In theory. Still waiting for the FINAL on 1 ...but way ahead. Words & Melodies 100% DONE on all but 1. Someday we'll track them."
Guitarist Adam Jones added on Instagram that "recording starts in April".
Metal singer Sebastian Bach has heard some of the Grammy-winning band's new ideas, calling it "progressive metal at its most atmospheric".
"Right when you get into a groovy trance you get beat over the head with riffs so heavy," he commented.
"Some tunes were so pummelling it felt like I was getting a deep tissue massage! in fact they could call the record that."
Tool are known for their lengthy waits between records. There were five years between Aenima and Lateralus, and another five between Lateralus and 10,000 Days.
It's been 4315 days since Tool's last record.
