There is a show, and it is written that they will perform
Gabriel Fauré, Requiem, op. 48
I searched on Spotify so I found that Requiem for Faure has too many op (i don't know how to call them) and there is also something called (Pavane) as you see
I just need to know which "song" is the one they will perform in order to see if i like so i go and buy the ticket
sorry if i use a wrong vocabular in music, i am so bad :(
