Billie Joe Armstrong has been a heavily slept on frontman since his early days in the band Green Day. From basements and back yards to sold-out stadiums, Green Day was punk for a generation, and the music they put out is still consistently good to this day. Billie Joe's ability to make a crowd feel like they are part of the show is almost intoxicating, he invites people on stage to play his guitar, he throws things into the audience, he'll even stage dive at his own shows at huge venues. People like to talk a lot of smack on Green Day since their departure from a traditionalist "true punk" sound, but for anyone that truly knows that band, they still have just as much energy as before.
