The Broadway musical “Spider-Man: Turn Off the Dark” will be performed as scheduled Friday night, a day after an actor playing the comic book hero was badly injured during the special effects-laden show. Producers blamed human error and the union representing actors vowed to investigate. “Tonight’s performance will go on as scheduled. The technical elements of the show are all in good working order, and we can confirm that equipment malfunction was not a factor in the incident,” said Rick Miramontez, a show spokesman.

The day features martial arts performances by Delta One Martial Arts of Antioch, East Bay Karate-Do of Pittsburg, Pallen’s Martial Arts and Solistic Martial Arts (both of San Pablo) and the AMAPA all-star demo team, Also on hand will be the Benicia Ballet Academy, local hip-hop group Born-2-Gig, Team Loopkicks’ ao49 ballet shoes patch kids baby girl ironing application patch patches size 2.7 x 7.0 cm martial arts champs and music by the First Baptist Church Gospel choir, Tickets are $10, For more info, visit www.amapa4kids.org, call 925-753-1167 or email amapa4kids@gmail.com..

Over the last decade (which included a three-season stint as composer-in-residence with the California Symphony in Walnut Creek), certain hallmark sonorities have emerged in his pieces. These include the whooshing surges of “Alternative Energy” (an “energy symphony,” Bates calls it, leapfrogging across centuries and continents, painting scenes from a 19th-century Michigan junkyard and a post-apocalyptic Icelandic forest) or the exquisite atmospherics of “Rusty Air in Carolina,” which evokes the chatter and buzz of katydids and cicadas, partially by using a vocabulary of blues and bent tones. And while his presence onstage has become a trademark, he has worked hard to craft his music in a manner that allows orchestras to comfortably perform without him. His scores come with a download link to the electronica parts, and his pieces have been played — sans Bates — from Oakland to Mobile, Ala.

“Berkeley Bowl and Costco delivery were the top requests from our East Bay customers,” said Instacart Chief Executive Officer Apoorva Mehta.
