The recently launched Tumblr blog, Experimental Music on Children's TV, is the work of Mike Haley from the cassette podcast Tabs Out. Though the project features contemporary shows, the most fascinating entries are YouTube clips of earlier children's programming. We see Mister Rogers playing an ARP Soloist (the Pro version was used by Vangelis and Tangerine Dream); we hear a frenetic, minimalist Philip Glass mini-opera for geometric groupings of animated circles in a Sesame Street short. Advertising composer Suzanne Ciani, a protégé of synthesizer builder Don Buchla and computer-music innovator Max Mathews, appeared on 3-2-1 Contact in 1980, to demonstrate the use of an Oberheim OB-X and a Sequential Circuits Prophet 5. REDEFINE chatted with Haley about the runaway success of EMoCTV and the inspiration behind it.
