NEW ORLEANS (AP) The start of the second weekend of the New Orleans Jazz and Heritage Festival was marked with thunderstorms, but the music played on.

Some went barefoot in the mud, while others dressed in rubber boots and rain gear on Thursday as they crammed together in messy fields and under tents to enjoy the variety of musical acts and genres.

By midafternoon, the sun poked through the clouds.

The headliners on Thursday included rocker Elvis Costello, rapper Flo Rida and the American roots band the Tedeschi Trucks Band, who were to play with Jimmie Vaughan and Billy F. Gibbons.

The weather was forecast to be better on Friday and Saturday.
