The transformation of Wales's Los Campesinos! from a sprightly indie-pop group into something far more wicked and weird has been a gradual one, but thankfully the band hasn't lost its penchant for writing catchy, clever songs. The prodigious, Cardiff-based band is touring in support of an excellent new album, Hello Sadness, with darker and more introspective songs than the group's exuberant earlier work. But the band's consistently dynamic live show should give these somewhat despondent new tracks a vibrant buoyancy. Los Campesinos! has amassed quite an impressive back catalog in a short amount of time, and should draw on a full complement of songs both new and old.
