Tool have debuted three minutes worth of brand new music.

An instrumental demo recording of the track Descending – which the band have played live for two years – has been used to accompany the promo video for an upcoming music clinic tour.

The tour will see the entire band (sans Maynard, who is on A Perfect Circle duty) interact with fans during intimate music clinic sessions in seven venues across the United States this coming May. Tickets are limited, and you can get all the details here. (via Consequence of Sound)

Watch the video below, which also features new visuals. Tool will release a new album later this year.
