Music

For 20 years now, Black 47 has been delivering its own brawny and bracing brand of Celtic rock. With a song called "Celtic Rocker" on its new album, the New York band takes an affectionately humorous poke at the musical style it has helped to popularize. After 2008's Iraq, a powerful grunt's-eye view of the desert war, the new album, Bankers and Gangsters, presents a more familiar mix of Larry Kirwan-penned material, distinguished by his gift for cinematic storytelling and an ability to shift nimbly between heavy and light subject matter. There are New York street tales, stories of Irish historical figures, outlandish adventures, and ballads steeped in sadness and loss.

Film

New this week:

Green Zone **1/2 (out of four stars) Matt Damon brings his Bourne gravitas (and box office) to this frenetic Iraq war movie, set shortly after the 2003 invasion. He stars as an intrepid Army officer on the hunt for WMD - and sorely disillusioned as he discovers all his intelligence on the problem is bad. R (violence, profanity, adult themes)
