Feelin' extra (staves)?

Two examples from Yvar Mikhashoff's virtuosic piano trilogy, Elemental Figures. 

If you thought Rachmaninoff's 4 staves was extra, Mikhashoff more than triples that! At first glance, I'd guess that Mikhashoff employs (/deploys?) an outrageous number of staves to graphically represent the explosiveness/expansiveness of the gesture. A glissando on two staves with 8va lines may sound the all the same but this does look significantly more striking (and ridiculous), which may offer something for the performer's psychology. 

To show stratification of voices, different "bells"... 

"Searched music"

• piano miniatures as avenues of self-discovery:
  • Boulez, Bartók, Schoenberg, Kurtág – experiments, sketches
  • Janáček, Schumann, Mompou – intimacy in microcosm, reaching for innermost sentiment
  • Ligeti, Musica ricercata, literally "searched music"/"found music"; striving for the creation of an Ur-self/Ur-language
    • Lachenmann (Ein Kinderspiel): composition as self-discovery; one must approach new frontiers of self in each piece, poetry of searching
      • Ein Kinderspiel both as "music for children"/"child's play", but also a "going back to the sandbox" approach to composition, invention of idiosyncratic approach to the piano
• form of ricercar – "searching" for key
  • Bach, Ricercars from the Musical Offering
  • Beethoven, String Quartet in B-flat (Op. 18/6), Mvt. 4 "La Malinconia", long searching introduction
  • Mozart, "Dissonance" quartet opening (arrival in C major)
• other "searching music"
  • Joni Mitchell (Blue, Hejira; "All I Want," "This Flight Tonight," "Amelia", "Hejira", "Let the Wind Carry Me")
  • Björk, "Hunter" ("if travel is searching / home what's been found / i'm not stopping / i'm going hunting")
  • Andrew Norman, "Try" (trial-and-error as a form)
