Radio is still an art at this 56-year-old institution. The oldest black radio station in Texas has ignored the streamlining so rampant elsewhere in the industry, so the station is all-local, all-the-time. Weekday mornings, 26-year-vet Michael Harris helms current affairs show "Person to Person"; afternoons are given over to the real-life moral dilemma dramas of Wash Allen's "Confessions" and Don Sam's soul, blues and zydeco oldies. Evenings bring Ralph Cooper's highly Houston-centric sports talk and plenty of grown-folks' music. As if all that were not enough, Mister Misty's stroke of midnight weekend performances are masterpieces of old-school radio theatrics.
