The line-up for Ozzfest won't officially be announced until later this week, but "Performance" magazine is reporting that Tool and Megadeth have been confirmed for the 1998 tour.

Meanwhile, media sources including "Performance" and the "L.A. Times" are reporting that Lollapalooza is negotiating deals with Green Day (who is also rumored to be negotiating a tour with Weezer), Garbage and Scott Weiland. The Cure is also reportedly under discussion, and there's been talk of the surviving members of Sublime joining the tour, although that band is thought to have died along with late singer Brad Nowell. The survivors have said they will not be replacing him.

This year, it appears that at least six headliners have rejected Lolla offers, including Nine Inch Nails and Marilyn Manson, the latter two because neither act could guarantee their albums would be finished in time. Manson's manager Tony Ciulla told the "L.A. Times" that the problem was timing: his client couldn't take a

chance and commit to touring. Sources close to Trent Reznor say that the latest Nine Inch Nails project is nowhere near being prepared to support a tour as early as the summer.

Ozzfest, organized by headliner Ozzy Osbourne, was one of the top two grossing festival tours of 1997. It will again feature Ozzy's own band as well as a reunion set from his old Black Sabbath alumni.

Lollapalooza didn't fare all that well last year, despite featured acts Tool, Prodigy, Snoop Doggy Dogg, Tricky, Korn and others.
