While there are many musical performers named Robert Horton, only one has a credit for performing on the amplified chair frame. That would be the Robert Horton who has performed as part of the group Fecund Now, a Pacific Northwest collaboration that has been featured on several volumes of the After the Flood series of compilations. His credit for vibrator, however, was trumped long ago by performers such as the Italian percussionist, composer, and conductor Andrea Centazzo. ~ Eugene Chadbourne, Rovi
