St. John’s Passion is a wise choice. I really get into Bach’s choral works (both oratorios and cantatas), especially this time of year.
I love St. Matt’s too, and Cantata 140, and the Christmas Oratrio, and cantata 147, and , and , and.
One day I got on YT and played Cantatas 1-213 one after another. Then I had to do other stuff, so I stopped. LOL.
Did I tell you I LOVE Bach?
