Girl from audience tears up stage at Green Day (Oakland, Aug. 5th 2017)
During Green Day’s cover of Operation Ivy’s “Knowledge,” Maddi Gruber was singled out of the crowd by lead singer Billie Joe Armstrong and brought on stage to play guitar with the band. YouTube will show you that Green Day does the all the time. Billie Joe give a quick lesson and then turns the spotlight to a guest and letting him or her do there thing before giving the guitar as a souvenir. What you won’t see on most of the videos is the audience member completely killing it like Gruber did. The 18-year-old went off, jumping around the stage with her green and blue hair flying around as she nailed the part like a pro.
