Music: Pop: USA's great sounds of the Hog Butcher capitol, Chicago, Chicago, Chicago

The Grateful Dead, a collection of their recordings (podcast date June 8,1969), one item among those that had been recorded in Boston, as early as June 8, 1976. Thereafter, at this city and that, webbing their performance travel out concentrically across the USA, urban American internal-migrants (both in- and out- migrants), a stratum of potential audience to whom the Dead agreeably catered. The band played Boston, Massachusetts, at the Centrum, featuring this 5-minute song, several musical stylings within it, and a pronounced quality for recalling Frank Zappa's album, The Grand Wazoo (1971). This song in our podcast archives, is a way-post to understanding the wherewithall of the spontaneous feelings that beg for recollection, rumination and clarification in this music.

I've been casting about, trying to post here a clickable audio podcast of the mentioned performance. But, so far, no luck.
