Justin Bieber and Selena Gomez Catch Tween Sensation Phish in Concert The Hollywood Reporter via Brad Sands Won’t you step into The Bieber … Worlds collided in California on Wednesday when noted hippies Justin Bieber and Selena Gomez attended a concert by the pop band Phish. Bieber’s guitarist and musical director Dan Kanter loves The Phish and convinced The Biebs to don his best Narc tie-dye and take in the show at the Long Beach Arena, the kickoff to the second leg of Phish’s summer tour. Alright, Internet, go mash up “Baby” and “First Tube.” NOW. The Hollywood Reporter had the exclusive: Wearing a green tie-dye T-shirt and a Philadelphia Flyers cap, Bieber was first introduced to Phish bassist Mike Gordon, then guitarist, frontman and Kanter’s personal idol Trey Anastasio. According to photographer Jeff Kravitz, they found common ground in talking music, of course, and also in singing the praises of Phish’s revered lighting director Chris Kuroda, who will be designing Bieber’s next tour [emphasis ours]. The couple also posed for pictures backstage with various members of the Phish extended family — and their children, naturally (see photo above, taken by longtime Phish road manager Brad Sands). For the second set, Bieber and Gomez really got into the (Weekapaug) groove, hurling glowsticks from a virtual arsenal they had stashed at the soundboard riser. Traditionally, a glowstick war breaks out at every Phish show. This one took place during the first two songs, “Rock & Roll” and “Ghost,” according to witnesses who noted, “they were having a blast.” Even though Bieber and Gomez left halfway through Phish’s second set, this might be how the chillbrahification of the former tween stars begins. One minute you’re all Disney’d up, the next you’re John Lennon and Yoko Ono inviting the press into your bed. Go forth, you sexy young’ins! • SEE ALSO: 12 Creatures That Look Like Selena Gomez’s Knee A clip of “Ghost” uploaded after the show by itstristanyo says “That actually is Bieber throwing glowsticks at 7 seconds, 13 seconds, and 1:09.” • SEE ALSO: Back to ’97: The Best Phish Shows…Ever Bieber is no stranger to Phish.
