"Lujon" (also known as "Slow Hot Wind") is a musical piece by Henry Mancini. It appeared on his 1961 album Mr. Lucky Goes Latin, but was an original piece of music that had nothing to do with the Mr. Lucky television program. It was included in the soundtracks for the films The Big Lebowski, Sexy Beast, W.E., and Two Lovers. Its name comes from the lujon percussion instrument heard on the recording.
Mancini would later record a jazz/swing version of "Slow Hot Wind" and include it on his 1975 album Symphonic Soul. The song would eventually reach the #38 spot on the Adult Contemporary list in 1976.
The lujon is a bass metallophone consisting of individually-pitched metal plates that are attached to the resonance chambers of a partitioned wooden box.
