There was a mini Nirvana reunion on Wednesday night in Eugene, Oregon as Krist Novoselic jumped onstage with Foo Fighters during the band's show at Matthew Knight Arena. They played "Big Me," from the Foos' self-titled 1995 album. (Billboard)

Political controversies from different musical worlds

The classical music world is buzzing over Minnesota Orchestra principal trumpeter Manny Laureano’s decision to stand up and walk offstage during a Rufus Wainwright concert on Saturday night at Orchestra Hall. Laureano, who is politically conservative, was offended when Wainwright expressed "shock" over the Republican-controlled House of Representatives passing a tax bill. "We have to fight for this country," said Wainwright to the audience.

"He's an angry dude that seems to have life all figured out, not the kind of guy we need to look to for philosophy," Laureano told the Star Tribune. "I found it to be beyond the pale of what that evening should be about. It's a time of the year we're supposed to all come together."

Meanwhile, Texas hardcore band Power Trip have tweeted "CEASE AND DESIST" after their "Executioner's Tax (Swing of the Axe)" was played on Fox News. The song was cited, apparently approvingly, by Greg Gutfeld — the guy whose show earlier this year led to the infamous Radiohead "strange, malnourished, and sad" designation. (Billboard)

Meet Me in the Bathroom to become a documentary

Author Lizzy Goodman’s much-discussed Meet Me in the Bathroom, an oral history of New York City rock in the early 2000s, is being adapted into a four-part documentary series. "The series, expected to be an hour per installment, will combine first-hand testimony and archive footage of many of the seminal bands during the period, namely the Strokes, LCD Soundsystem, Interpol, and the Yeah Yeah Yeahs," notes Billboard.

Producer Pulse Films hasn't yet announced how the documentary will be distributed. Catch up on our Rock and Roll Book Club feature on the book.

Mariah's back in the Top 40

Mariah Carey is back in the Top 40...with guess which song? Yep, it's her 1994 holiday hit "All I Want for Christmas Is You," which lands at number 21 this week. It's been a regular visitor to the Top 40 in recent years — it peaked at number 11 in 2015 — but it actually never hit the Hot 100 upon its original release, since by the rules in place at the time, a song had to be released as a commercial single to make the chart.

In other chart news, Voice contestant Chloe Kohanski has broken the Hot 100 with her version of "Total Eclipse of the Heart," making this the fourth different rendition of that song to become a hit. Nicki French (1995) and the Glee cast (2010) both took it up the charts, but only original songstress Bonnie Tyler (1983) hit number one with the song. (Billboard)

Ed Sheeran, MBE

Superstar Brit Ed Sheeran has been named to the Most Excellent Order of the British Empire — so it will be Mr. Ed Sheeran, MBE who will be playing U.S. Bank Stadium next fall. It's quite the honor, but it doesn't make Sheeran a knight, so he's not Sir Edward...yet. The singer-songwriter said that Prince Charles asked if he was still selling a lot of records. Yes. The answer is yes. (Billboard)
