Dr. John is the guest on this week's Jamie Cullum show from BBC Radio 2. Dr. John, whom Cullum calls one of his "true musical heroes" and “the coolest guy in the universe,” discusses his life and career and his new album, Locked Down, which the Boston Herald names Album of the Week. "It’s voodoo rock, dense, strange, tangled, beautiful in its darkness," says the Herald. "It also adds wild, welcome new flavors to the gumbo. West African highlife grooves Fela would flip for are everywhere. ’60s Stax soul sneak in during select choruses and bridges. Shaft-style funk drops in for a few druggy intros and outros." The A.V. Club calls it "an inspired collaboration ... at once classic and modern."

The Joshua Redman Trio, featuring bassist Matt Penman, a member with Redman of the band James Farm, and drummer Gregory Hutchinson, kick off a week’s residency at the Village Vanguard in New York City tonight. "Joshua Redman has lately put his tenor and soprano saxophone to work in the context of James Farm, a superarticulate postbop quartet, with strong direction from all four of its members," says the New York Times. "He returns to a more ostensibly hierarchical trio format here ... The results should be sleek and full of silvery digression." James Farm has a four-night run at the Blue Note in Tokyo next month. Redman and Brad Mehldau conclude their own duo tour next week.
