I believe there is, however I could be incorrect. Are you talking about this person's music, artstyle, or personal appearance? I can answer more accurately the comments if you can provide this information. :)
The concerto was a popular form during the Classical period (roughly 1750-1800). It had three movements – the two fast outer movements and a slow lyrical middle movement. The Classical concerto introduced the cadenza, a brilliant dramatic solo passage where the soloist plays and the orchestra pauses and remains silent.
I believe the answer you’re looking for is existentialism :)
I am pretty sure it is D, Metered Rhythm.
