The name Joe Ruler comes up just a few times in jazz, coincidentally involving exclusively players from the trombone. A later on trombonist acknowledged with several sessions through the hippie period used the nickname “tailgate”, descriptive from the device itself. A youthful tailgater called Joe Ruler performed and documented with the good traditional blues] vocalist Ethel Waters, amongst others. Ruler may possess reigned over many device families, obtaining credits not merely on trombone but on clarinet and tenor and soprano saxophone. These details is within mention of early Waters classes in the ’20s, nevertheless, and may derive from somebody not composing a name down. Columbia’s Tribute to Dark Entertainers compilation offers a hearty family portrait of this studio room scene, Ruler in good fettle on Waters’ family portrait of “Dinah”.
