Dmitri Shostakovich's epic series of preludes and fugues for solo piano was inspired by the very composer whom you would immediately suspect – Johann Sebastian Bach. Indeed, the Russian composer was motivated to write this huge work after a visit to Bach's home city Leipzig in 1950; and, in fact, it resurrects the premise behind Bach's "The Well-Tempered Clavier," providing one prelude and fugue for every major and minor key. So having conquered the Bach work on recordings, Keith Jarrett decided to tackle its 20th century sequel in this two-CD set. Looking at it from one angle, this is Jarrett's most impressive technical achievement in the classical repertoire so far. Generally speaking, the Shostakovich is more difficult to play than the other classical works that he had recorded previously, and he is clearly up to all of its sometimes fearsome demands.
