Speed-metal pioneers Anthrax [ tickets ] will hit the road in January for a month-long tour that will feature both Joey Belladonna, former lead singer who was booted from the band in 1992, and John Bush, Belladonna's replacement and former Armored Saint frontman.

The band, touring in support of its latest album "Return of the Killer B's (A's)" (Beyond Music), will feature Belladonna on the band's older songs, while Bush will handle vocals on the more recent material. Both lead singers will perform on the band's rendition of the Temptation's classic "Ball Of Confusion," which appears on the album.

The band's 17-city itinerary begins on Jan. 16 in Springfield, Va., and concludes on Feb. 5 in San Francisco.

''Return of the Killer B's (A's)" is a 16-track greatest hits set that covers the band's 14-year history. The title is a play on "Attack of the Killer B's," a compilation of b-sides and rarities released by Anthrax in 1991.
