"While Tool‘s rather verbose November newsletter led many to the conclusion that Tool were in the studio with Joe Barresi, it turns out that’s not entirely true. As was cautiously posted before, the newsletter only confirmed that members of the band had been in the studio with Barresi; with Tool material being directly specified much later.
A key revision to said newsletter over at Toolband.com has since revealed that the recordings in question were in fact for Tool drummer Danny Carey‘s side project VOLTO! and not Tool. Yep, bummer."
