Jimmy Buffett / Merriweather and Nissan Pavilion He's more than just a clever singer-songwriter.

Tickets are available through Ticketmaster. 50 Cent and Jay-Z / Nissan Pavilion They're two colossal forces in hip-hop: 50 Cent, rap's hot boy at the moment, and the charming, prolific Jay-Z.

Unlike the classical-music world, where the fall concert schedule is announced and put on sale months in advance, there's generally not a lot of advance notice for autumn pop concerts. Indeed, most of the area's major venues, such as the Baltimore Arena or the MCI Center, look as if they'll be quiet for most of the season. Don't be fooled. There are, indeed, concerts coming. Big ones, too. But not all of them are on sale yet, or have been formally announced. So even though every 'N Sync fan knows the group will be playing the MCI Center in Washington Nov. 11, the official word is that the promoters are still in negotiations with the band.
