$10 Tuesday?

Tomorrow from 10 a.m. to 10 p.m., LiveNation will be offering $10 tickets to a bunch of shows at the Tweet and the Pavilion. Act of generosity? Simple promotion? Sign of softness in the summer concert biz? All of the above? In any case there are discount tix available for good shows like Willie Nelson/John Fogerty, the Download Festival with the Dropkick Murphys, the Black Eyed Peas, the Allman Brothers, Santana with Jeff Beck, Chris Isaak, Ziggy Marley and more. Tix at the box office, Ticketmaster and ticketmaster.com.
