"The Low Spark of High Heeled Boys" (1971) is the fifth studio album by the rock/jazz outfit Traffic. It was released at the turn of the decade and gathered much praise, partially due to the album's incorporation of reed (woodwind) instruments and jazz influences along with rock and roll, combining two of the most popular types of music during its day. Produced by guitarist/organist Steve Winwood, the album's title track would become the most well known song from the release, with a version edited due to time constraints receiving moderate airplay. This album is also different in another way, since it is the only Traffic album to include two lead vocal performances by percussionist Jim Capaldi on both "Light Up or Leave Me Alone" and "Rock and Roll Stew".
