Just as I remembered it when I bought their Blatently Offensive EP in the late 70's, which also included a subtle gem called Toilet Love. Truly they pushed back the boundaries.
I really like the last section of the opening - glittering - but isn't the beginning a bit more dramatic and declamatory? I love hearing Bach played on the piano, but I think it's good to imagine what he would have heard on the harpsichord.
Excellent phrasing and dynamics. A really good performance.
