New album expected in early 2007.

Fifteen years after its first album, pioneering U.K. "trip-hop" act Massive Attack is hitting the road to promote "Collected—The Best of Massive Attack" (Virgin).
The act will play late-April U.S. dates in Seattle, Denver and Indio, Calif. (at the Coachella Festival), booked by Monterey Peninsula Artists. June sees U.K./European dates, handled by International Talent Booking, ahead of appearances at Japan’s Summersonic festivals in Osaka and Tokyo (Aug. 11-12).

Massive Attack put aside work on its long-awaited fifth studio album—tentatively titled “Weather Underground”—to promote “Collected,” Virgin Records U.K. product manager Ben Curwin says. “Weather Underground” is now expected in early 2007.

“Collected” had a U.K./international release March 27 and a U.S. release April 4. It includes one new track, the recent U.K. hit “Live With Me,” while a special edition features rare/unreleased material.

A major multi-media campaign has helped U.K. shipments approach platinum (300,000 units), Curwin says. “All activity has been in conjunction with long-lead tastemaker and grass-roots marketing to reinvigorate fans and target the huge potential lapsed fan base,” he adds.

Universal Music Publishing Group/Island Music handles Massive Attack’s publishing.
