The first time I heard J.S. Bach's Well-Tempered Klavier, I heard an endless sameness, lovely but undifferentiated. Only over many hearings did each pairing of prelude and fugue begin to emerge from the background, as what Bach did in each iteration of the same received form began to be revealed as an inexhaustible richness of difference. Gradually, I was learning Bach's musical language; only then did I begin to get an idea of what he might be saying.

I came to Jane Siberry's music pretty late in the game. This is her fourth album, and the third released by a major label—No Borders Here and The Speckless Sky were released by Open Sky/Windham Hill a few years ago. Hadn't heard 'em (footnote 1). Didn't need to. On the basis of The Walking alone, it was clear Siberry is one of the most important singer/songwriters we've got.
