Jazz From Hell

Jazz from Hell is a Grammy Award–winning instrumental album from Frank Zappa. It was released in 1986 by Barking Pumpkin Records (vinyl) and by Rykodisc (CD).
All compositions were executed by Frank Zappa on the Synclavier DMS with the exception of "St. Etienne", a guitar solo excerpted from a live performance of "Drowning Witch" from a concert in Saint-Étienne, France on Zappa's 1982 tour.
"While You Were Art II" is a Synclavier performance based on a transcription of Zappa's improvised guitar solo on the track "While You Were Out" from the Shut Up 'n Play Yer Guitar album. The unreleased original Synclavier performance was done using only the unit's FM synthesis, while the recording found here was Zappa's "deluxe" arrangement featuring newer samples and timbres.
"Night School" was possibly named for a late-night show that Zappa pitched to ABC; the network did not pick it up. A music video was made for the song.
"G-Spot Tornado", assumed by Zappa to be impossible to play by humans, would be performed by Ensemble Modern on the concert recording The Yellow Shark.
