The New Philadelphians recorded their sole 45rpm single Mustang for the local Quaker City Jazz label in the late 1960s. And what a monster it is. 8 minutes of smokin' soul-jazz at its best. If someone would claim this was an unreleased Jimmy Smith Blue Note recording from 1969, no one would doubt it. More information about Charlie Chisholm and the band can be found on Tramp's Movements Vol.10 compilation album.
