@richardbrand for large orchestral works by Bach, possibly try Nederland's Bach Society. I heard them play the Mass in B minor in Berkley. Hearing it on gut strings at a' = 415 Hz, HIPP played, that is a whole new experience. They recorded it, though I don't have that 2x CD.
Baroque playing is not about playing loud with vibrato sauce, but about gestures such as trills and note shaping (messa de voce, much easier to do with baroque bow than with modern Tourte bow). Listen for the type of trill used (starting upper/lower note, turn at the end, speed change, number of oscillations) and also variation on repeats, which are typically not written out, as the performer was expected to improvise "in the usual manner". Classical orchestras are clueless about all of the above. That's why they compensate by playing loud and hide their ignorance with vibrato sauce.
Current audiences are by and large clueless and just like loud music. I went to a Los Angeles Chamber Orchestra "Baroque series" concert, where the musical director massacred a piece on the grand piano, did not even keep the lid on, utterly killing the theorbo's fine plucking by Master Schneiderman. Theorbo and plucked harpsichord form the Basso Continuo portion of the orchestra. Con-certare (playing together) went out the window, just me-me-me. It was viscerally painful. The carnage got a standing ovation, because it was loud and loud = good.
