Allen Toussaint, who celebrated his 71st birthday last week, celebrated once more at the 2009 Celtic Connections festival Monday at Glasgow's finely refurbished Old Fruitmarket. Scotland's Herald gives the performance five stars, exclaiming: "Toussaint produced the kind of gig for which this venue was saved. Funky, celebratory and above all downright real, Toussaint's music has the spirit of a Mardi Gras street party running through it and the Fruitmarket is, after all, only one generation of slight gentrification up from being a street itself."

John Adams led the Pittsburgh Symphony Orchestra, of which he is the Composer of the Year, in two concerts this past weekend at Pittsburgh's Heinz Hall. Featured on the programs were Doctor Atomic Symphony, On the Transmigration of Souls, and selections from Nixon in China. The Pittsburgh Post-Gazette says the composer "has penned some of the best music of the last quarter century" and "gave us a reason to be proud again of the splendor that can emerge from 100 orchestral musicians. He is a composer of our time." The Pittsburgh Tribune-Review calls Transmigration "awesome and haunting to experience" and Doctor Atomic Symphony "a masterly new piece."

The New York Times recommends the concerts, saying that the album's double-trio format leads to "a result that feels rewardingly loose ... the sort of jazz interaction that can only be further clarified by live performance."

The day I tried it, the Gretsch guitar, I knew very quickly that that was the sound I was looking for."

The Evening Standard gives the album four stars as well, stating that Redman's "writing and playing is brilliantly lucid."
