Rarely do I watch or read talks written so densely and passionately. This lecture by a Christian violinist for the Boston Symphony Orchestra covers so much ground I don’t know where to even begin. For one thing, she nails what is missing in the Evangelical church’s love with popular culture and contemporary music. It is well worth the 15 minutes, but I warn you, it takes some undivided listening to really hear all the important things Ms. Ostling has to say.
