Friday’s column is about all the teens singing and building sets for an opera, “The Magic Flute,” for Saturday’s one-off performance in Pomona. More details (and audio clips) can be found on the website of the Pomona-based Repertory Opera Company.

The English pop band the xx performed a sold-out show Wednesday at the Fox Theater in Pomona between dates at the Coachella festival. Above are bassist Oliver Sim, foreground, and guitarist Romy Madley-Croft, left, the band’s principals.

Very moody and atmospheric stuff, as the lighting hints at, and the audience ate it up. There were screams as if we were watching the Beatles. I was curious to see them because several of my friends are big fans, and critics love them too, but I haven’t connected, at least not yet. They did put on a good show and seemed genuinely touched by the rapturous response: “Again and again and again, thank you so much,” Sim said earnestly toward the end.

On the floor, it seemed like half the fans had cell phones or cameras to take photos or record videos, as the picture below indicates. In front of me, both halves of a couple viewed the show almost exclusively through tiny screens. What, can’t they share a single video later? Try to coexist (to quote the title of the band’s latest album)!

Something’s coming soon to the old Arby’s in Pomona, but it’s not a restaurant. Rather, a Boost Mobile store will occupy the Conestoga wagon-shaped building at 2250 N. Garey Ave. Arby’s opened in 1970 and closed in May 2012, taking its charming ten-gallon hat-shaped neon sign with it.

Richard Nichols, who alerted me to the sign, joked: “For $55 a month you get unlimited everything, including Horsey Sauce.”

Above are Jenny Lewis and Ben Gibbard of the pop group Postal Service, performing at the Fox Pomona on Monday night. Excellent show and my new favorite band. Is it possible to say that about a lineup that released its one and only album 10 years ago? It was reissued with bonus tracks last week, and purchased by yours truly, who had never heard of them until recently. The band has reunited for a spring tour and Coachella festival appearance, but probably not for new recordings. Well, I love them anyway.

They performed every song off their album (how could they not have?) but in arrangements that were more urgent and guitar-driven. Beautiful stuff.

Below, fans congregate outside the Fox afterward. Third Street is blocked off at Garey and Thomas streets, allowing fans to take photos of the blazing marquee without fear of traffic. A nice touch.

Pomona’s Glass House and Fox Theater music venues have hosted acts playing at Coachella for years now, but this year sees the most “Localchella” shows yet. Sunday’s column gives you the details and notes the effect on downtown Pomona of thousands of visitors, night after night.
