Morton Feldman - Piano and String Quartet (1985, rec. 2011)
After all that excitement, let's take the tempo down... right dooowwwwwnnnn. Morton Feldman's late work in particular is an acquired taste, and it really takes work to adjust your brain to take it in. If a normal album or even a regular symphony is like watching a river flow past, or like crashing waves, music like this is akin to watching an Arctic glacier for signs of movement.
I had already heard the Kronos Quartet/Aki Takahashi recording (1993) of Piano and String Quartet some time ago, but on buying this 2011 disc by the Eclipse Quartet last year I've found it much more satisfying. Just 80 minutes of pensive piano lines and pointilistic strings to get lost in, or to do the washing up to - the latter being part of my first experience of the Kronos version.
