Parks underwent unsuccessful hand surgery in 2014, causing his hands to freeze after about forty minutes of playing piano. On May 9, 2015, Parks performed what he called his "final piano performance" at the Largo in Los Angeles. Guest performers included singer Gaby Moreno; songwriter-producer Joe Henry; Grizzly Bear's Edward Droste; New Zealand singer-songwriter Kimbra; and jazz guitarist-composer Grant Geissman. Of upcoming projects Parks said: "will set poetry to music, to underscore poems. So I will still be performing once I get that done. I will be looking to find a celebrated string quartet to take things to an irreducible minimum. I can pick up a quartet in Peoria, or in Europe, to perform something like this. I also hope to find a film project that interests me."
