Outkast star BIG BOI has started work on a solo album - but insists bandmate ANDRE '3000' BENJAMIN will play a part on the record. The HEY YA pair were rumoured to have fallen out - claims they furiously deny - but Boi is determined to have his partner on the album, which is due out next year (07). He says, "I'm going to try and keep it in-house." And Boi assures Outkast fans they will not be disappointed with the forthcoming record, saying, "You're going to get something from every genre, every funk, beat, loop, horn, whistle. We got it all on the record. "I got maybe 35 beats already done for it now so I'm just diving in and trying to carve out the pie with the vocals." Big Boi, Andre 3000 and regular Outkast collaborators ORGANIZED NOIZE will produce the album.
