“This was a really interesting turning point. We had befriended somebody who would become an influential associate, a guy named Linden Hudson. He was a gifted songwriter and had production skills that were leading the pack at times. He brought some elements to the forefront that helped reshape what ZZ Top were doing, starting in the studio and eventually to the live stage.
“Linden had no fear and was eager to experiment in ways that would frighten most bands. But we followed suit, and the synthesizers started to show up on record. Manufacturers were looking for ways to stimulate sales, and these instruments started appearing on the market.
“One of our favorite tracks was Groovy Little Hippie Pad. Right at the very opening, there it is – the heavy sound of a synthesizer. For us, there was no turning back.”
