Inspired by Oliver Sacks's fascinating exploration of atypical mental states, Five Hallucinations , Carl Vine's trombone concerto, was premiered in October 2016 by Michael Mulcahy and the Chicago Symphony Orchestra under James Gaffigan. Each movement of the 20-minute concerto is based on a different hallucination, from the ominous "Doppelgänger" to the rather absurd "The Lemonade Speaks."
