In a good jazz rhythm section, the players function independently and as one. Their parts and accents crisscross and reinforce each other, interlocking like West African drummers. Beyond that, the bass is a band's ground floor. When it changes up, the earth shifts under all the players' feet.

AIDS is the primary killer of African-Americans ages 19 to 44, and the mortality rate is 10 times higher for black Americans than for whites.

Tired of regular old hamburgers and hot dogs for July 4?

You're in luck. On Tuesday's Fresh Air, Jack Bishop and Bridget Lancaster from America's Test Kitchen join Terry Gross to highlight some of their favorite grilling techniques and summer recipes — everything from meats to vegetables to, yes, even desserts.

If there was any doubt that The dB's have any use for being considered through the haze of memory, or limited to the misty fondness from fans who remember them from the early 80s, the blast that opens their new album Falling Off the Sky, a song called "That Time Is Gone," could not be more explicit. Group leaders Peter Holsapple and Chris Stamey, along with drummer Will Rigby and bassist Gene Holder, are taking back their sound after 30 years, sprucing it up and re-exploding it for the days we live in now.
