What happens when four teenagers from LA get on stage at the Vans Warped Tour? They get asked to perform at all stops on the tour. Echosmith, fronted by 16-year-old Sydney Sierota and her brothers Noah, Jamie and Graham, has been playing to enthusiastic audiences and receiving overwhelmingly positive response. Possessing great stage presence and a lot of maturity, there’s definitely no sibling rivalry in this band. Just some very talented and “Cool Kids.”
