Just as the '80s saw a hard bop/post-bop revival that was unofficially led by Wynton Marsalis, the '40s and '50s saw a Dixieland revival. As a rule, the artists who came out of the Dixieland revival movement of the '40s and '50s had no interest in playing bebop, which was new and cutting-edge at the time. They were unapologetically retro, and their playing was a throwback to the New Orleans and Chicago jazz of the '10s and '20s. One of the Midwestern bands that came out of that Dixieland revival movement was the Original Salty Dogs, which was formed at Purdue University in West Lafayette, IN, in 1947. At the time, bebop was the new kid on the jazz block, and Charlie Parker, Dizzy Gillespie, and Thelonious Monk were as controversial as John Coltrane and Ornette Coleman would be in the '60s. But the Original Salty Dogs (not to be confused with a traditional bluegrass band called the Salty Dogs) had no interest in playing bop or even swing; their influences included King Oliver, Louis Armstrong (his pre-swing material), Jelly Roll Morton, and Bix Beiderbecke (among others). Whether they were playing standards or original material, the Midwesterners were consistently mindful of the Dixieland artists of the '10s and '20s (although they do have their own sound).
