Query: Screaming Strings; Jarring Chords

Sylvie Courvoisier's Abaton can only be understood and appreciated by trained musical geniuses or pretentious bores. What most fans of European chamber jazz would recognize as melody is non-existent on this double (and double-priced)CD.Courvoisier's piano is background on all of the 22 tracks in this collection almost serving as a base line for the violin and cello. However, that would imply that these tracks follow some sort of structure and they don't. The piano here just bangs out an occasional thumping cord as a counter-point to the wailing strings.Even ECM can't bat 1000 but Abaton is a joyless dirge of noise that is occasionally punctuated by a silence that may make you hope it's over and you can get on with your life.
