Massive Attack have posted a track from their upcoming joint single with Burial online.
The group have collaborated with the London DJ on the split 12" 'Four Walls/Paradise Circus', which sees him remixing two of their tracks.
'Four Walls' is a brand new track, while 'Paradise Circus' appeared on their 2010 album Heligoland.
The limited edition vinyl version of the single will be released on October 17, but all 1,000 copies have already been sold out online.
Burial released his latest single 'Street Halo' earlier this year, as well as collaborations with Thom Yorke and Four Tet.
Massive Attack recorded a track with actress Scarlett Johansson earlier this year for the soundtrack to Mexican movie Days of Grace.
