The 2010 Proms in London had an all-Bach day this month. We'll hear two very different highlights: a sizzling performance of the Brandenburg Concerto No. 2 from conductor John Eliot Gardiner and the English Baroque Soloists, featuring some stellar trumpet work by Neil Brough. And the world premiere of a new piece inspired by Bach, "Latent Manifest" by Tarik O'Regan. O'Regan says he followed the "implications" of the "intimations" in the slow movement of the Solo Violin Sonata No. 3 by Bach. Andrew Litton leads the world premiere performance by the Royal Philharmonic Orchestra.
