Titled "The Hook" after an onstage cue frequently employed by FZ during this period, Volume 4 of Scott Parker's acclaimed Recordings Of Frank Zappa series dissects the recordings of Zappa during what fans refer to as "the Roxy period" from the fall of 1973 through the spring of 1974. At 247 pages, and available in both black and white and color variations, it is without question Parker's best work to date.
