A month ago, the Colombian band Aterciopelados -- the velvety ones -- held a small premiere party there. Picture the scene. The room is filled with local fans -- eager to see the band's latest video release.
Many of those present already know the song. It's a tight-knit community that's formed around Colombia's best-known indy-rock act.
They warmly greet the band's two core members, Andrea Echeverri and Hector Buitrago. Then Andrea and Hector step up to the mic to introduce the new video for "Rio."
The song refers to the river that runs through Colombia's capital.
In Vitro regularly holds video nights. The club even has old movie theater seats loosely scattered around the place for a more comfortable viewing.
The video itself is pretty cool: a mix of stop-action animation drawn on a sheet of glass that was framed over various parts of Bogota where you'd find water and then filmed.
