Four posthumous Bob Marley & the Wailers sets -- "Rebel Music," "Talkin' Blues," "Legend," and "Natural Mystic" -- will be reissued May 21 by Island/Tuff Gong/UME in digitally remastered versions, replete with bonus tracks and the original artwork and liner notes.

All four albums were released after Marley's death in 1981, and each highlights a different aspect of his storied career. "Rebel Music," originally released by Tuff Gong in 1986, collected some of Marley's most politically charged songs, such as "Get Up, Stand Up," "Slave Driver," and "War/No More Trouble." The bonus track "Wake Up & Live (Parts 1 & 2)" will be included on the new version.

"Talkin' Blues," originally released in 1991 on Tuff Gong, is a critically acclaimed document of Marley & the Wailers' first U.S. tour. The majority of the album's tracks are taken from a radio broadcast from a 1973 performance on San Francisco's KSAN-FM, interspersed with interview excerpts. The new reissue will include three previously unreleased bonus tracks from the KSAN broadcast: "Lively Up Yourself," "Stop That Train," and "Bend Down Low."

The 1984 Tuff Gong hits collection "Legend" is the biggest-selling reggae album of all time, having been certified by the Recording Industry Association of America for U.S. shipments of 10 million copies. Its 14-song summation of Marley's career -- strewn with hits like "No Woman No Cry," "I Shot the Sheriff," and "Redemption Song" -- has been augmented with the 1978 track "Easy Skanking" and a non-LP studio version of "Punky Reggae Party." "Legend" is the only one of the new reissues to feature expanded packaging, with additional photos, liner notes, and lyrics.

Finally, "Natural Mystic: the Legend Lives On," a 1995 Island sequel to "Legend" that concentrated on album tracks, will be updated with the bonus track "Positive Vibration." The four reissues are part of an ongoing archival program by Island/Tuff Gong/UME, which issued remastered versions of the Marley albums "Uprising," "Survival," and "Kaya" in July 2001.
