NEW YORK (AFP) - Guns N' Roses, whose reunion tour is expected to be one of the year's biggest live attractions, on Wednesday tapped Lenny Kravitz and Alice In Chains as opening acts.

Guns N' Roses singer Axl Rose and guitarist Slash last month played together for the first time in more than two decades and will set off on June 23 on a tour of North American arenas.

Alice In Chains, who emerged in the heyday of Guns N' Roses in the mid-1980s and marked a transition from metal to Seattle's grunge scene, will play starting on the tour's first date in Detroit.

Kravitz, an acclaimed multi-instrumentalist who has merged blues and R&B into his hard rock sound, will take over in Boston on July 19, although the band did not announce opening acts for a number of the concerts.

Guns N' Roses, shaped by Rose's soaring range and raw anger coupled with Slash's intricate guitar, still hold the title for the top-selling debut album ever with 1987's Appetite For Destruction.

After years of feuding, the band played a small gig in its native Los Angeles in April followed by the Coachella festival in southern California.

The full-fledged tour will start after Rose wraps up a tour of Europe with Australian hard rock titans AC/DC.

The band chose Rose as its surprise new singer after frontman Brian Johnson was told that he risked hearing loss if he kept performing.
