If you’re a Strokes fan, Primavera Sound is the place to be this weekend. Three Strokes-related acts are playing the Barcelona festival — the band, Julian Casablancas + The Voidz, and Albert Hammond Jr. — and there’s bound to be some weird encounters. Case in point: AHJ watched on as Julian Casablancas and the rest of his solo band turned the Strokes’ “Vision Of Divison” into an abstract mess, and his reaction is priceless. It’s not the first time the Voidz have done the song live — they did it last week at a show in Hollywood — but it’s definitely worth a look. Watch the whole performance below — AHJ’s reaction is at 3m43s.
