More on the thought-provoking, circuit-straining arts created via technology. Are you ready to enter new virtual environments and meet the artists behind them? Here’s part 4 of our 5-part series.

Ideas about what art is are always evolving. Throwing “electronic” into the mix seems to get things going even faster! In this episode of What You Didn't Know, see how the world of art continues to change as electronic art becomes a prevalent art form. But with all the controversy about whether or not electronic art is a valid art form, some try to keep in mind that the message is the most important thing.

In the song “Mentiras,” or “Lies,” by the Venezuelan band Los Amigos Invisibles, a girlfriend hears rumors about her boyfriend going out with other women, but he tells her the rumors are pure lies. Who’s the real liar? Watch the video to find out. Shot in a bar in New York City, the camera follows the lead singer of the group around and “mockuments” the evening he sings about.

This group formed in 1991 to fill a gaping hole in the Venezuelan club/dance band scene. They have a Latin Grammy under their belts as well as nominations for Grammys and Latin Grammys. Move to the beats of “Como sabes tú” from the album Commercial.

"Toda la vida" ("All My Life") is the theme song which opens the Colombian version of the American hit series The Wonder Years. The song is a cover of a hit Italian song,"Tutta La Vita", written by celebrated composer Lucio Dalla. Sung by Mexican singer Emmanuel, this version was number one on the Latin charts for three weeks in 1984, replacing a different version of the very same song sung by Cuban singer Franco.

It's the summer of 1985 and 12-year-old Kevin González is spending his time playing banquitas, a Colombian form of street soccer. His older brother, Leo, is forever tormenting him, while his best friend, Fede, does his best to intervene.

Los Años Maravillos incorporates genuine archival news footage, giving us a sense of what it was like to live in Colombia in the mid 1980s. In this segment, we see reports regarding the civil conflict involving rebel forces used as a backdrop to the family drama unfolding at the González dinner table.

Unlike Kevin and Fede's previous school, this one is co-ed, arousing some anxiety in them. Fede even confesses about a nightmare in which he arrives at school naked.

Kevin's neighbor and childhood playmate, Cata, is starting the same school as Kevin and Fede. But she is sporting a new, more mature style and insists that she be addressed by her full name, Catalina.
