In this week's Audiograph we head to San Francisco's Fillmore district, once known as the 'Harlem of the West,' jammed with clubs overflowing with song. While the district has changed over the decades, reverance for one musician in particular has not — a tenor saxophonist who has been canonized and praised for half-a-century. The St. John Coltrane Church celebrated it's 50th anniversary this month.
