Chuck Brown is music's answer to baseball's iron man Satchel Paige. Born in 1936, Brown earned his only Top 40 hit at age 43 and still regularly performs. He's a barn-storming ex-hobo who used to play for food but stuck around long enough to become a good-time ambassador for his community. He is also, as much as one person can be, the originator of a musical genre: go-go music, a hybrid of big-band '70s funk, multi-drummed Latin percussion, gospel call-and-response, horn-section jazz, old-school rapping and DJ-like song segues that evolved in Washington, D.C., through the '70s. In 1979, Brown's Soul Searchers topped the R&B chart with "Bustin' Loose," but he had already been playing in soul and Latin bands since the early '60s. In 1984, "We Need Some Money" went No. 26; 23 years after that, "Block Party" got to No. 60. But Brown never stopped band-leading -- in fact, of his 15 or so albums since 1985, about half were recorded live. Most came out on tiny local labels, with minimal distribution beyond D.C.; many have overlapping setlists, frequently incorporating cover selections spanning the past 70 years of black music. To Chuck Brown, it's all one big party.
