 You may listen to charming, cheerful Baroque music and assume that the composers were charming, cheerful people. And many of them, most of them, certainly were. But sometimes composers and performers are a little more free-spirited. They thumb their noses at tradition and a few, including Johann Sebastian Bach, even found themselves on the wrong side of the law. You'll hear music by some renegades on Sunday Baroque this weekend. Sunday morning at 7 on WSHU Public Radio.
