Alrock James Duncan

Al Duncan (October 8, 1927, McKinney, Texas — January 3, 1995, Las Vegas) was an American drummer and songwriter. Music critic and musicologist Eugene Chadbourne described Duncan as a "forefather of rhythm and blues" and "one of less than a half dozen key studio legends of the 1950s and 1960s who have sometimes been called the 'grandfathers of groove'." Chadbourne credited Duncan as helping develop the characteristic metric feel or timekeeping of rhythm and blues.
