Other musical influences are experimental hardcore band Melt-Banana, which toured with Mr. Bungle in 1995, post-rock band Sigur Rós, country singer-songwriter Willie Nelson, the recording of vocals by João Gilberto, composer Olivier Messiaen, especially his transcriptions of birdsongs, and cartoon music composer Carl Stalling, who was a shared point of reference with John Zorn, whose PhD thesis was on him. The singer expressed fondness for Mauricio Kagel's "negation of opera and the whole tradition of music theater" and Mark Mothersbaugh's music in the "Crash Bandicoot" game series.
