Though at first it may seem odd to imagine Varese, a... classical... orchestral composer as one of Zappa's most strong influences, upon further inspection it becomes clear. Simply to look at his face...
... is telling enough that in some way or another, Zappa would find inspiration from this man. He has the hair and face of a mad scientist and the piercing eyes of someone confident in his creations; a confidence needed when composing music that most listeners and even more fellow composers considered "noise" and not at all music.Looking closely at some of Varese's compositions we see more tangible similarities between his and Zappa's tastes. Like the young Zappa to follow, Varese employed the use of noise (timbre) and rhythm in a sort of collage fashion, moving in and out of themes, often changing metre and adopting a whole new theme. These changing themes would often seemingly have little or no correlation between them and would sometimes last only seconds before morphing into something entirely new and unexpected. It was exactly this stylistic approach which Zappa would use in the epic "Lumpy Gravy".
Here is one of Zappa's most beloved Varese compositions, "Ionisation":
Compared to part 1 of Frank Zappa's "Lumpy Gravy":
Zappa's piece, like Varese's, has a strong sense of rhythmic unity combined with various changing timbre's. In both pieces we are initially put off by the apparent lack of any attention paid towards structure, but, upon further listening, we see the unparalleled ability of both composers to string together unrelated elements of themes, rhythm and timbre into a cohesive whole.
Although at first it may have seemed odd to find a copy of Edgard Varese's Ionisation amongst Zappa's record collection beside the likes of Clarence "Gatemouth" Brown, The Cadets, and The Coasters, now we are able to see a clear link between the two styles of music.
