Deguello

Degüello is the sixth studio album by the American rock band ZZ Top, released in November 1979. It was the first ZZ Top release on Warner Bros. Records and eventually went platinum. It was produced by Bill Ham, recorded and mixed by Terry Manning, and mastered by Bob Ludwig. Returning from a two-year hiatus, the band began to showcase the influence they had collected during the time away; Gibbons' time in Europe introduced him to punk music, the influences of which seeped into the creation of the album. The band also consciously tried experimenting with technology: Gibbons saw an episode of The Phil Donahue Show where a person's identity was protected using silhouette and a pitch shifter; liking the sound, he asked engineer Manning to call the show and find out what the effects unit was. Manning eventually convinced a reluctant show producer to reveal it, and the effect was used for both vocals and guitars on songs like "Manic Mechanic".
