NEW: This set is now (October 28, 2009) up on Naxos Music Library.
These classic performances of the string quartets were nominated for Grammy and Latin Grammy awards in 2002.
This is a great bargain for a six-CD set ($45 at Amazon.com). Amazon mentions that the set includes a DVD along with the CDs, but I don't have any details as yet.
There was a previous compilation of these string quartets from Brilliant Classics - 6634(CD)
