"Blue Rondo a la Turk" was the flip side of the single which featured the Dave Brubeck Quartet's all time greatest hit, "Take Five." Inspired by the rhythms of Turkish music during a tour of Europe, Brubeck blended this exotic rhythm with the classical rondo form and the blues in the unusual time signature of 9/8 to create this still challenging masterpiece. The members of the group were well up to the demands of this piece, which has been recorded by Brubeck on numerous occasions as well as remaining in his play book for several decades. Most of the jazz interpretations by others pale considerably next to the original, though the Turtle Island String Quartet did a superb job with their arrangement. Less successful are versions by pop musicians and singers, especially the watered down 4/4 setting recorded by the Nice (who also were credited with writing the piece they called "Rondo").
