Harrison Brady Overdrive, or "HBO" (not to be confused with HBO, the premium cable channel that offers such fine programming as "The Sopranos", as well as a number of other shows that contain lots of swearing, that being the whole raison d---etre of cable television), is a string/percussion duo consisting of Randal Harrison and Geoffrey Brady. Employing such instruments as the violin, the vibraphone, Randal's vocals, the theremin, the electric cuica, and the chincello, HBO features improvisations based on the original compositions of the duo's (two) members, as well as EXCITING NEW interpretations of the works of such diverse composers as Debussy, Piazzolla, Schoenberg, Monk and others. Plus, HBO, like HBO, uses a lot of profanity and charges a reasonable fee for this service.
