Fiona Apple addressed things right away Friday night at Bayou Music Center.

She apologized to someone for being "attitude-y" Thursday morning, then called out four others for acting "inappropriate and probably illegal." No names. No further details.

Apple (whose last name is Maggart) was arrested Wednesday at a border stop in Sierra Blanca, where a drug-sniffing dog found small amounts of hash and marijuana on her tour bus. She was held overnight at the Hudspeth County Jail and released Thursday after posting a $10,000 bond.

Sierra Blanca is the same place where Willie Nelson, Snoop Dogg and actor Armie Hammer were arrested for drug possession.

Apple stormed onstage just before 10 p.m. in a floor-length dress, her hair pulled back in a messy ponytail. She's alarmingly frail but was energetic and enthused. She launched into "Fast As You Can" with aplomb, under a blaze of flickering lights before settling in behind her piano.

Her voice is unlike any in contemporary music, veering from growling and guttural to sensitive and soulful. She clipped the ends of each line in "Shadowboxer" with a sneer, then followed it up with a downright joyous "Paper Bag."

"Anything We Want" was an early standout from “The Idler Wheel ...," her first album in seven years. The song's defiant hook -- "We can! Do anything! We want!" -- was like a rallying cry.

Apple drew heavily from that album during the almost 90-minute show. "Periphery," another new track, built on a rollicking piano arrangement with drums and playful vocals. It segued into early single "Sleep to Dream," which drew cheers and one of several crowd sing-alongs.

Some of the heavy arranging ran together at times, but her songs have a strong hold over 20 and 30-something girls in thrift-store dresses, who swayed in the aisles and sang along.

"Extraordinary Machine" was another vocal showcase, and "I Know" had the slightest twang that made it feel lost and lonely. Her voice trembled into the microphone during swooping single"Every Single Night," and she pounded on a drum at the end of "Daredevil."

Apple didn't address the crowd again until after a haunting, gorgeous cover of Conway Twitty's "It's Only Make Believe," and it was just to offer a quick thank you. She left the stage and the lights came up, even as the crowd chanted her name and shouted "Criminal." Maybe next time, she'll be more in the mood for that song title.
