Kronos String Quartet

Listening to string quartet music has been a passion of mine for four decades.  One particular string quartet group that I have really enjoyed is the Kronos Quartet based in San Francisco.   They have been performing for over 40 years, with three members remaining from the original group. 
I have purchased nine of their albums and have seen them twice in concerts in Los Angeles.  Recently, I purchased two more albums by this creative, versatile, and prolific string quartet.  

Alban Berg's Lyric Suite performed by the Kronos Quartet, 2003.   The Lyric Suite is a six-movement work for string quartet written by Alban Berg between 1925 and 1926 using methods derived from Schoenberg's twelve-tone technique.  This pensive quartet is less than 30 minutes in length.  

Philip Glass's String Quartets 2-5, performed by the Kronos Quartet, 2005.    Philip Glass (1937-) is a noted and prolific American composer of music with repetitive structures.  The harmonies in this album are very appealing.
