Not bad if a lot of fuzz and wah-wah wanking is your thing.
Um, yeah. Or try this...
"Another solo over a vamp, here in E Mixolydian. The vamp does I-II-VII in E Mixolydian, while the bass gives an E pedal note. The sound of the guitar and some of its licks are remindful of the "Easy meat" solo from "Tinsel town rebellion", recorded about a week later at Santa Monica, December 1980. The vamp returns with variations and extensions as a concert opener on "The best band you've never heard before" (see the corresponding section).
In Guitar Player, October 1995, Zappa comments upon the fact that a bass pedal note or the key of a vamp doesn't prescribe a keynote for his solos:
GP: "Heavy duty Judy" sounds as if it's based on more than one tonality.
FZ: I do that all the time. For instance, that's just an E7 vamp, and I like to play in the key of A. It's just like playing in the tonality of the eleventh [extending E7 to A would create an 11th chord on E].
GP: That can be pretty hairy for someone used to playing only major and minor chords and 7ths.
FZ: They are missing out! The fun doesn't start until you get at the eleventh.
GP: Further complicating the piece are the many different rhythms.
FZ: Well, basically, in that tune you've got the band - bass, keyboards and rhythm guitar - playing the same shuffle rhythm, and the guitar and drums are going apeshit on top of that, but always knowing where the downbeat is going back. That doesn't mean you have to play the downbeat, because everybody else is doing it - playing hemiolas across the bar".
Shut up 'n play yer guitar
