I remember leaving 5 Seconds of Summer’s Sounds Live Feels Live tour last summer and telling my friends Hey Violet was on the brink of success. So would you believe that just eight months later I was hearing them perform sold-out show? When I saw the group, they were a four piece but now with newest bandmate, Ian Shipp, they’re on their first U.S. headlining tour and made a little stop in Dallas, Texas where they performed at the Cambridge Room in the House of Blues.
