Jimmy Buffett / Merriweather and Nissan Pavilion

He's more than just a clever singer-songwriter. Jimmy Buffett is a smart businessman, whose reach goes beyond platinum-selling albums and into clothing lines, nightclubs and literature. His concerts still draw huge crowds. Buffett plays Merriweather Post Pavilion tonight at 8. Tickets are $36-$66. He also stops at the Nissan Pavilion on Saturday. Show starts at 8 p.m., and tickets are $36-$66. 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. The two headline the Rock the Mic tour, also featuring Missy, Busta Rhymes and Fabolous. The show stops at Nissan Pavilion Sunday night at 6. Tickets are $34-$50 and are available through Ticketmaster by calling 410-481-SEAT or visiting www.ticketmaster.com.
