(Radio.com) Linkin Park were scheduled to  play Good Morning America last week as part of the show's summer concert  series. The tragic death of vocalist Chester Bennington made that  impossible. So instead, Toni Cornell, the daughter of the late  Soundgarden vocalist Chris Cornell joined One Republic's Ryan Tedder  onstage to sing the Leonard Cohen classic "Hallelujah" in tribute to  Toni's father and Bennington. Both performers took their lives earlier  this year.

"It's an honor to  perform this for my dad and Chester and to sing for them," Toni told the  crowd. "Chester sang this at Chris' funeral, and this is arguably one  of the greatest songs written in the last 50 years," Tedder added.

The  performance was touching and heartbreaking and Toni's clear and  poignant vocals revealed more than a bit of her dad's DNA. Members of  the crowd became teary as photos of Chris Cornell and Bennington flashed  on a screen. Adding to the emotion was the Soundgarden shirt Toni was  wearing, which served as a constant reminder of the loss she and the  rock world suffered when her father died. 

(Radio.com) Incubus fans in New Orleans got a special surprise during last night's concert: The band brought Solange onstage to duet with Brandon Boyd on the song "Aqueous Transmission."

The move wasn't entirely random. Several months ago, Solange revealed in an interview with Teen Vogue that, as a teenager, she dreamed of marrying the rock band's frontman Boyd.

 Guitarist Mike Einziger shared a selfie with Solange after the show, writing "Thank you so much for playing with us tonite."
