James Blake and Vince Staples are once again extending their collaborative relationship with a new version of Blake's single "Timeless" arriving Friday, now featuring a guest verse from the Long Beach rapper.

The pair first debuted the track earlier this summer at Glastonbury, but this is the first time they've released the studio version. The original edition of "Timeless" appeared on Blake's latest album The Colour in Anything, which arrived back in May.

The Staples-assisted "Timeless" comes just a day after Blake announced the MC will join him on select dates of his North American tour. It's also not their first collaboration, as Blake co-produced Staples' Prima Donna EP, which was released last week.

As midnight Friday hits in different parts of the globe, the song has surfaced on iTunes and it is expected to be available in the U.S. late Thursday.
