Miles Dewey Davis III (May 26, 1926 – September 28, 1991) was an American jazz musician, trumpeter, bandleader, and composer. Widely considered one of the most influential musicians of the 20th century, Miles Davis was, together with his musical groups, at the fore front of several major developments in jazz music, including BeBop, Cool Jazz, Hard Bop, Modal Jazz, and Jazz Fusion.
With their second album, Rio Grande Mud, ZZ Top uses the sound they sketched out on their debut as a blueprint, yet they tweak it in slight but important ways. The first difference is the heavier, more powerful sound, turning the boogie guitars into a locomotive force. There are slight production flares that date this as a 1972 record, but for the most part, this is a straight-ahead, dirty blues-rock difference. Essentially like the first album, then. That's where the second difference comes in – they have a much better set of songs this time around, highlighted by the swaggering shuffle "Just Got Paid," the pile-driving boogie "Bar-B-Q," the slide guitar workout "Apologies to Pearly," and two Dusty Hill-sung numbers, "Francine" and "Chevrolet." There are still a couple of tracks that don't quite gel and their fuzz-blues still can sound a little one-dimensional at times, but Rio Grande Mud is the first flowering of ZZ Top as a great, down-n-dirty blooze rock band.
