In the 1960s through 1980s, producers of audio recordings were striving to achieve something which they called “Wall of Sound”, which I suppose was influenced by producers like Phil Spector’s releases with the Beatles. It is a dense, all-encompassing sound with the drums, bass, guitars, keyboards and sometimes vocals too having equity in the mix, and not too much separation from left to right but a spacious “soundstage” effect, and just a solid onslaught of music for the duration of the track.

Well, there was a legend about a certain band fronted by Stan Ridgway. In the late 1970s they were in the studio and the producers were tweaking knobs and sliders to approach the desired sound. And one of them asked whether it was a “Wall of Sound” yet, but another replied, “it sounds more like a Wall of Voodoo!”
