Gagarin is an original composition written by Dr. Daniel Eichenbaum as part of an live performance at the Gottleib Planetarium in Kansas City Missouri on February 5th and 6th 2011. The performance, by Dark Matter, combines electro-acoustical music and full-dome video projected on the Planetarium's 19 meter dome. This video, Gagarin, is an audio and visual tribute to Yuri Gagarin and those who followed him in orbiting the Earth. The quotes are as accurate as possible. This is a flat-screen version of the original.
