Damon Albarn works with Massive Attack

Massive Attack's new album 100th Window is to feature a guest appearance from Blur's Damon Albarn.

The long-awaited follow-up to 1998's Mezzanine album is now complete, and due for release in early 2003 following a single Special Cases.

The band's frontman 3-D has recorded most of the LP alone, along with guests including Sinead O' Connor and Horace Andy.

Albarn has recorded a part for an as-yet-untitled song that will feature on the record, according to NME.com.

Albarn and 3-D recently worked together in a campaign to prevent US-led attacks on Iraq.
