i went to see Los Campesinos! with my good, and aforementioned, friend matt on monday night, they were absolutely amazing. i would recommend that anyone should try and catch one of their shows. both of the support acts were really top notch, Sparky Deathcap and Copy Haho. Copy Haho were just my thing, almost Johnny Foreigner-esque, kind of melodic indie hardcore. Sparky Deathcap is also part of the live Los Campesinos! set up, whether that's due to convenience or a permanent fixture I neither know or care, either way they were BLOODY AMAZING.
i also met gareth (the lead singer) of Los Campesinos! he's actually a genuine sweetheart, although post-gig sweaty-face photos are always grim.
