As a teaser to the Bristol group’s upcoming fifth album, this package of highlights spanning their 16-year career is right on time. The seductively spooky “trip-hop” genre Robert Del Naja and his collaborators helped to create remains a defining sound of the ’90s; but that term doesn’t begin to sum up the influence of decades of soul music lurking in Massive albums from Blue Lines to 2003’s 100th Window. Their new single, “Live With Me” (featuring Terry Callier), is included on the first disc of band-picked favorites (as well as tracks like “Karmacoma” and “Unfinished Sympathy”). Disc two hits and misses with simmering, unreleased tracks and so-so soundtrack tunes, but its flipside offers every MA video to date.
