Last Sunday, Lon Schreiber, at First Baptist Church of the City of Washington DC played the second of the three Prelude-and-Fugue pieces from Op. 37 by Felix Mendelssohn, the Prelude and Fugue #2 in G Major. I remarked afterward that it really does sound like Bach. Screiber let it end fortissimo, but this YouTube performance ends it quietly.
I found that Op. 36 was the set of six Prelude-and-Fugue for Piano. When I was a senior in high school, I was able to play #1, in E Minor. The fugue breaks out into a heroic chorale in the Picardy E Major toward the end. Serkin ends quietly, but I seem to remember bringing the volume back for the close.
When I was in graduate school in the mid 1960s at KU, my roommate had a record player and one classical record, a Columbia of Biggs playing, among other things, the Bach G Major Prelude and Fugue, BWV 541..
