Not to be confused with the jazz trombonist from the '20s, this Robert Horton's contribution to swinging music was to concoct an album cover in which composer and multi-instrumentalist Anthony Braxton's face is sliced up and mounted onto four equal-sized postage stamps. Horton's work, perhaps looking forward to the era when Braxton will appear on stamps, was used as the cover on a collection of Braxton compositions recorded by the Bay Area ensemble Splatter Trio. ~ Eugene Chadbourne, All Music Guide
