Tell Us The Truth, Boston -- Sunday night's excellent installment of this traveling music & politics roadshow was a refreshing gust of wind across the grassroots, despite its multifaceted message. Media consolidation, free trade, Iraq, peace, love, parenting, Janeane Garofalo, what more could you ask for? I am once again totally crushed out on Billy Bragg -- we all agreed he spoke as eloquently (but of course less mendaciously) as Tony Blair, with a dash of Woody Guthrie, and of course the electric guitar added a lot to his look. The surprise of the night was the sonorous singing voice of Tom Morello, formerly known only for his mighty axe-wielding in Rage Against the Machine. To me, he was channeling Bruce Springsteen on "Nebraska," but the Globe's assessment ("Johnny Cash-Leonard Cohen") is true too. If anyone can make a song called "Maximum Firepower" sound vulnerable, it's him. Right on! Check out the tour site for more details...
