Los Amigos Invisibles + City of the Sun

On its latest single "Tócamela," Los Amigos Invisibles sound like Venezuela's answer to Daft Punk, with retro synths blaring atop a funky bassline and jittery guitar riff (all that's missing is a bit of vocoder accompaniment). The trio has been making buoyant dance music since 1995, signing to David Byrne's Luka Bop label and accumulating a boatload of Latin Grammy nominations along the way. Flamenco-inflected insturmental rock trio City of the Sun opens this free Millennium Park Summer Music Series concert.
