A planned SXSW performance by the Roots on Saturday night was canceled after organizers received a bomb threat via e-mail. Although police didn't locate any threat near the Fair Market venue, sponsor Bud Light decided to err on the safe side and cancel the show. 26-year-old Trevor Weldon Ingram was subsequently arrested and charged with making a terroristic threat.

Remembering Nokie Edwards

Guitarist Nokie Edwards has died of an infection at age 82. Edwards's signature twang was a key early influence on the genre of surf rock.

Edwards started as bassist in instrumental rock icons the Ventures, then switched to lead guitar when his bandmates recognized his skill on that instrument. After the switch, the band rerecorded their breakout hit "Walk — Don't Run," and the new version became a hit in its own right. He was inducted into the Rock and Roll Hall of Fame as a member of the Ventures in 2008. (New York Times)

Rihanna blasts Snapchat

However much Snapchat was paid to run an ad inviting viewers to "slap Chris Brown" or "punch Rihanna," it wasn't worth the $800 million in market value its parent company lost after Rihanna blasted the social networking app for showing the ad.

The ad was made by the creators of the online game "Would You Rather," but had to be approved by Snapchat in order to be viewed. The company apologized for approving the ad, which alluded to Brown's 2009 assault of Rihanna, but Rihanna did not accept the apology.

"Shame on you," she wrote on her Instagram story. "Throw the whole app-oligy away." (Billboard)

Congrats to David Byrne

David Byrne has a top ten album for the first time since his days in Talking Heads. His new album American Utopia lands at number three on this week's Billboard 200, thanks to...yep, concert ticket bundling. While Byrne can celebrate his album sales, he's not celebrating his omission of female contributors: he's issued a statement saying he regrets not collaborating with any women on the album.

Arcade Fire on SNL

Arcade Fire were this past weekend's musical guests on Saturday Night Live. In addition to playing two songs from their latest album Everything Now, they appeared in a skit starring host Bill Hader, who played a fictional Canadian producer who resigns from his job for very mild misbehavior that makes him "a monster by Canadian standards." All six members of the band show up to personally apologize for doing a song for a soundtrack from the producer. (Billboard)
