"This Eminent is a Dutch build organ with a String Ensemble on the top layer. It was actually one of the first string synthesizers. It was build in 1972 and it is very well knows as the typical 'Jarre' synthesizer. Actually most sounds on his 'Oxygene' album come from this organ run through some phasers like the Smallstone and Mistress from EHX."

Note the Alesis A6 on the far right. I don't think Sequential Circuits is represented. If anoyone sees one, feel free to comment. Also I'm not sure what the box is between sets on the right. Looks like a Linndrum, but that could be the lighting.
"This special 45 minute edition examines the leviathan synthesizer introduced by RCA engineers in 1955, and features electronic sounds created only with the Mark 1 and 2 machines. Included are tracks composed by Otto Leuning, Vladimir Ussachevsky, Milton Babbitt and Charles Wuorinen." You'll find it at the bottom of this post.
