Included on the 1979 album Sheik Yerbouti, "Rat Tomago" is not a composition, per se. This is a guitar solo edited from a performance of "The Torture Never Stops" in Berlin, February 15, 1978. Those familiar with the song will recognize the tempo, the bass motif, and most of all the female moans faintly heard in the back. The way the guitarist starts with a melodic line and gradually develops it gives the track almost a stand-alone feel. This is the first occurrence of such an edit in Zappa's body of work. He will often use the same technique in later years, especially for the albums Shut Up 'n' Play Yer Guitar and Guitar, but also occasionally throughout the You Can't Do That on Stage Anymore series.
