“There was a disconnect to Mercury Soul that couldn’t be solved, no matter how clean the cross-fade between DJ and orchestra. The audience was entreated to dance to standard-issue house music and pedestrian pop fare (“Billie Jean,” Prince’s “Controversy”), but only for 15 minutes at a time. Meanwhile, Roumain shredded on his violin — impressive and novel, certainly, but not particularly conducive to dancing. There were also conflicting codes of conduct — the audience didn’t know exactly when to applaud, clap along to the beat or talk among themselves.”
