Challenging Jazz Duets, Volume 1 is a set of five jazz duets for players of multiple combinations of instruments. The purpose of these duets is to provide players challenging arrangements based on the chord changes to standard jazz tunes. The song titles are an obvious allusion to the titles of their related standard jazz tunes: Riding the Rails (Take the A Train); Red Salsa (Blue Bossa); In a Mellow Way (In a Mellow Tone); Singing for Pops (Song for My Father); G-Man Blues (Standard Concert F Blues).
