5. ROCKIN' IN RHYTHM (DUKE ELLINGTON/IRVING MILLS/HARRY CARNEY) 3:01
In his Musician article, Pareles described Weather Report's live performance of "Rockin' In Rhythm" like this: "In a night of curveballs at the Beacon, the most unexpected one was that Weather Report actually played a cover: Duke Ellington's 'Rockin' In Rhythm.' It was perfect, not only for its title, but for the way the band tore into it. They treated its bluesy line as they'd treat anything Shorter or Zawinul might have come up with, hard and swinging, while behind it Zawinul punched sustaining modal Fender Rhodes chords off the beats in a trademark style. In totally regrooving Ellington, Weather Report asserted their continuity with jazz tradition, simultaneously proving they had something of their own to add to it." [M80]
In a 1997 article for Jazziz magazine, Josef Woodard described Zawinul warming up for a rehearsal in his home studio with a "knuckle-busting voicing of Duke Ellington's 'Rockin' In Rhythm.'" "You've gotta be able to play keyboards," Zawinul told Woodard. "It's a lot of thirds."
