There are a couple of different kinds of music that Bach composed. Of course he is well known for his chorales, but based on your comment those probably don't speak to you. What might be a better place to start would be the cello suites. The first is so well known that it's hard to come to it with an open mind. But my favorite is the second in d minor. Here is a performance by Mischa Maisky: https://www.youtube.com/watch?v=ki9ySiWQNu8 https://www.youtube.com/watch?v=ki9ySiWQNu8 Much more lyrical and passionate than we often associate with Baroque music. Bach is, of course, very well known for his counterpoint, which probably is why a lot of technical people like his music so much. I personally like these pieces best on organ. The fugues in particular are always a great deal of fun as each line comes in and the piece gets richer and richer. Here is a performance of the Great Fugue in G major: https://www.youtube.com/watch?v=6clTa8_QYQE https://www.youtube.com/watch?v=6clTa8_QYQE I think there's really no substitute for listening to these pieces live, though. With a good organ you just get enveloped in the sound. The next best thing to do is wear good headphones and really crank up the volume, but headphones just can't match the bass of 64 foot pipes. I'd also be remiss if I didn't mention the Chaconne from his partita for violin: https://www.youtube.com/watch?v=HEbi-7tPaqo https://www.youtube.com/watch?v=HEbi-7tPaqo
