--Green Day's Billie Joe Armstrong Seeking Treatment For Substance Abuse

Green Day frontman Billie Joe Armstrong is seeking treatment for substance abuse after his shocking onstage tantrum at the iHeartRadio Music Festival on Friday.  The band announced the news on their official Facebook page Sunday and also apologized for offending the festival.  Armstrong went on a tirade at the concert in Las Vegas Friday night. He was apparently angry with iHeartRadio Festival organizers for cutting his set, which the band now says did not actually happen.  They also announced that they will be postponing some of their upcoming appearances.  Although they acknowledged that Armstrong is getting treatment for substance abuse, Green Day did not provide specific details nor did they address the status of their upcoming tour.  

News of Armstrong's outburst and rehab entry comes a few weeks after the Green Day rocker was reportedly hospitalized before a concert in Bologna, Italy.  The band cited illness at the time.  A few days later they resurfaced to perform at the MTV Video Music Awards in Los Angeles on September 6th.  Green Day's latest album "Uno!" will be in stores on Tuesday.


--Fiona Apple Accuses People Involved In Arrest Of Wrongdoing

Fiona Apple is accusing some of officers who took her into custody of behaving in "inappropriate" and "probably illegal" behavior.  During a concert in Houston on Friday, the singer-songwriter opened up about her recent drug bust.  Fans captured some of the impromptu speech on cell phones. Apple was arrested last Wednesday when police in Sierra Blanca, Texas found hashish and marijuana in her tour bus.  She later admitted the drugs were hers, and opened up about her brief stay at the Hudspeth County Jail at one of her following tour stops.  She told the crowd she didn't have a problem with most of the people she encountered during the incident, and even apologized to the man who runs the jail for being "attitudey."  But Apple alluded to four people who she claims engaged in wrongdoing, adding that she took note of all their names and everything they said and did.

Apple explains that, at least for now, she has no plans to release the specific names of the wrongdoers.  Instead, she says she's keeping all that information in a "lock box" that she'll only open if any of them start to become, quote, "interested in being a celebrity."


--Swedish House Mafia Call Breakup An "Experiment"

The Swedish House Mafia guys aren't quite sure about their post-breakup plans, but that's exactly how they want it.  The DJ trio is set to announce the dates for their farewell tour today, and Sebastian Ingrosso tells "Rolling Stone" they made the decision to call it quits in hopes of creating "some sort of chaos" for themselves.  However, his bandmate Steve Angello says their new "experiment" doesn't mean the three DJs won't meet up again in some other combination somewhere down the line.  Angello jokes that they might even get back together as a trio and just call it something else.

In the meantime, Swedish House Mafia is focusing on their upcoming trek and its matching soundtrack, "Until Now."  The album is due out October 22nd.


--Trent Reznor Side Project Signs With Columbia, Announces EP

Trent Reznor and his How to Destroy Angels cohort are teaming up with a major label and promising fans new music.  The Nine Inch Nail frontman's side project -- which also features his wife Mariqueen Maandig and frequent collaborator Atticus Ross -- recently announced a deal with Columbia Records.  Reznor released his last few albums independently, but explained in a Facebook post that the indie option "has its great points but also comes with shortcomings."  He says they spent a long time thinking about joining Columbia, but ultimately decided "it makes sense for a lot of reasons."  He didn't share all of them, but says it comes down to the trio trying new things to see what best serves their needs.

Now that they have a home, How to Destroy Angels is set to release a new EP titled "An Omen."  The six-song collection will be out digitally and on vinyl November 13th.  Videos and live show dates are expected to be announced this fall as well.


--Bon Jovi Guitarist "Sorry," But Doesn't Remember Green Day Gig

Bon Jovi's Richie Sambora is offering an apology of sorts to Green Day.  Green Day's Billie Joe Armstrong recently said performing with Sambora's group was the worst concert experience he's ever had.  Sambora tells "Rolling Stone" he's sorry that Armstrong had such a bad experience, but adds that he's not sure what the Green Day singer is talking about.  The guitarist admits he has no recollection of Green Day ever opening for Bon Jovi, but admits he might have been "incapacitated" at the time.  He adds that despite Green Day's bad experience, he still wants to support up-and-coming acts by bringing them on the road with Bon Jovi.

Meanwhile, Bon Jovi has some new music on the way.  At last weekend's iHeartRadio Music Festival, frontman Jon Bon Jovi told "Billboard" the group has their next album ready for release.  The band worked on the project with their longtime producer John Shanks.  Bon Jovi said the disc should be hitting stores in the spring.  The new studio effort will be the group's follow up to their 2009 disc "The Circle."  The singer added that Bon Jovi is contributing two songs to the upcoming film "Stand Up Guys," starring Al Pacino and Christopher Walken.  The film is due in theaters in January.   


--Led Zeppelin Discuss The Release Of "Celebration Day"

Led Zeppelin's Jimmy Page says the upcoming release of the concert film "Celebration Day" wasn't something that was pre-planned.  The guitarist explains that they only taped their performance because it "made the utmost sense" to do so. Bassist-keyboardist John Paul Jones adds that the timing of the release is also natural.  "Celebration Day" documents Led Zeppelin's critically acclaimed headlining performance at London's O2 Arena in December 2007.  While five years has elapsed since the event, Jones says that's "like five minutes of Zeppelin time."  "Celebration Day" will receive a big screen presentation at participating theaters on October 17th, following several premiere events throughout the world.  The movie will then be released in a variety of audio and video formats on November 19th.
