Congratulations. The brandenburg concertos are impossible not to like. Acoustics wise, I'm not a fan of churches as they were not designed for ensemble music.
Due to all the hard surfaces, and a rectangle, the reverb has a long life. I would suggest listening to the concertos ahead of time, and what you may notice is they may play it slower to allow for the reverb to decrease, otherwise you have a mix of current plus previous.
So if you like it a little, my suggestion is to see a piece at a music venue.
In a music venue, small ensemble, no sound system, it can sound great. You hear all the instruments, and the audience is quiet.
Good luck.
