My son and the Alban Berg String Quartet

Congratulations to the father. Thanks to you your son as a broad vision of music, with no prejudice about XX century music.
As for a recording I recomend for the Quartet and the Lyric Suite a reading under the Alban Berg String Quartett, on the EMI label.

You dont let him wear that bow tie and derby to school do you?

He insists!

Count your blessings. Wish I knew a kid like that or had one in my family.
