The fourth album from OutKast, Stankonia, is scheduled to come out in June, according to a LaFace Records spokesperson.

The record, mostly self-produced, is the follow-up to the Atlanta natives' widely acclaimed 1998 effort Aquemini. Ray Murray of the Atlanta production trio Organized Noize said he and his partners had advised OutKast rappers Andre and Big Boi through the making of the record and helped arrange songs.

Not holding back, Murray said the album was "beyond anything that's commercial" and "the baddest thing to come out in music" in years.

Murray described one track, "Bombs Over Baghdad," as sounding similar to Run-D.M.C.'s 1986 hit remake of Aerosmith's "Walk This Way" and said other songs use guitar as well. Organized Noize produced songs on Aquemini, 1996's ATLiensand 1994's Southernplayalisticadillacmuzik.

OutKast are known for the Southern blues and soul influences in their music, for their quick, off-kilter rhyming style and for their use of live instrumentation. Their most famous single is "Rosa Parks" (RealAudio excerpt), a funky club track driven by an agile acoustic guitar lick and a chorus that encourages club-goers to leave "the back of the bus" to dance. The real Rosa Parks, who helped fuel the civil-rights movement by refusing to sit in the back of a segregated bus in Montgomery, Ala., in 1955, sued the group last year for using her name. She eventually lost the case.
