Despite trying to live up to heavy buzz, Swedish electro pop duo Lo-Fi-Fnk gave a lukewarm performance. Coming off like your little brother’s first band, vocalists and multi-instrumentalists Leo Drougge and August Hellsing were like two giggly karaoke patrons with too few Radio Shack toys. It was good enough to sway to, but their set was too casual and breezy to compare to last year’s album Boylife.
