The Smoking Gun got its hands on Katy Perry's 45-page concert rider. Boy, does this little lady have some really big demands, including that her driver not try to talk to her, and no carnations ever!

Last night, HBO premiered the highly anticipated Lady Gaga Presents the Monster Ball Tour: At Madison Square Garden, a 120-minute concert special—filmed over two sold-out February nights—that showcased the pop star in the core of her element: Performing for thousands of adoring fans, on her own terms and with an off-the-charts level of spectacle only Gaga can conjure up.

File this under "the medium is the message": At a teeny-bop concert in Ecuador, Miley Cyrus performed the world's most incongruous rendition of Nirvana anthem "Smells Like Teen Spirit." I say this as someone who once witnessed a violin-flute duo called Nerdvana at an Illinois summer camp talent show in the '90s.

A 20-year-old Oklahoma woman killed and mutilated her family's cat, apparently so she could use its blood for an outfit to wear to a Lady Gaga concert. Talk about a "little monster"! But seriously, she killed a cat.

Monday was the last night of musician/god Prince's run of concerts at Madison Square Garden, and because he is Prince, and does what he wants, he invited large-busted socialite Kim Kardashian to dance with him onstage (around 1:00 in the video). But she didn't dance! Instead, she stood there and pulled that awkward-pretend-laugh-oh-God-I'm-so-uncomfortable move that is a favorite of people who can't dance, or don't want to embarrass themselves trying.

Serious question — Who pays $80 to see Cheap Trick? Also: They're still around?

One of the highlights of Usher's OMG tour is when he selects a lucky audience member to come on stage for a serenade. Not any more. Watch this woman who accidentally kick the singer in his face with her heel!

Usher brings a fan onstage to serenade her. Sexily, he takes her into his arms. Reclining, she grinds against him, then lifts her leg and flicks her foot over his head, stripper-style—only to kick him in the face.

Jersey Shore cab-yeller DJ Paulie D will actually DJ an upcoming gig in New York. No one's ears are safe.

Hating Sarah Palin is a personal hobby of mine. But there are lines even I won't cross! GWAR—shock rockers who dress like Transformers at a swingers sex club—recently "went there" by disemboweling Sarah Palin in effigy on stage.

Japan isn't exactly known for being normal, we know this. But did you ever think you'd see a concert—attended by thousands of screaming fans—that starred an anime-like hologram? Whether you did or not, here it is. Watch inside.

During one of her recent performances, Lady Gaga saw a fight break out at the front of the stage while she was performing. She shouted to stop the music and broke up the fight on her own. Well played, Gaga!

Irish fans were so irate that Guns N' Roses (or Axl Rose and his current back up band) were late to a gig, they booed and thew bottles until the band left. Finally, the appropriate response to Guns N' Roses!

A group of 100 Russian skinheads stormed a crowd of concertgoers on Sunday, reportedly killing a 14-year-old girl. Details are still sketchy, but local media is reporting that some 100 people were injured while police "were inactive or ran away."

A concert over the weekend in Colorado turned ugly when fans began rioting, burning down vendor tents and throwing people through windows. This might sound like a Juggalo event, but no... it was a Earth, Wind & Fire concert.

Wednesday: man plummets onto Phish stage. Thursday: man jumps to death at Swell Season show.

Sheryl Crow is dedicated to saving the planet. That's great! But the rider for her current tour is so Draconian in its green policies that it's driving concert promoters nuts. Does she really care that deeply about toilet paper?

At a recent radio concert, professional Day-of-the-Week underpants moistener Justin Bieber was talking to his adoring fans when one detractor decided to chuck a water bottle directly at his face. There is no reason to post this except, ha ha.

Singer Pink—who has this whole thing she does, with a harness, in the air—had to stop a concert in Germany tonight when she wasn't clipped in properly and fell into a barricade. She's okay! Just "seriously sore." [People]
