This deeply moving account of the work can well match the acclaimed RCA recording by Tashi Quartet. Main difference is that Shaham's ensemble allows more freedom of expression for individual instrument and every movement is much slower than Tashi ( DG Timing 3'01 / 5'31 / 8'51 / 1'43 / 10'00 / 5'38 / 8'18 / 9'17 ).
Another advantage of this recording is the very realistic sound quality of each instrument. I'm particularly pleased with the piano part which has amazing presence throughout the music, providing rich, almost orchestra-like sonority, well balanced with other three instruments (not restrained as mere background support like in so many other recordings).
Shaham's rendition of the last movement is one of the most moving performances I ever encountered, capturing the sense of infinity and eternity so profoundly like no other violinist could do. Commentary includes facinating account of musical life surrounding the first performance, by one of the musicians who gave premiere concert in the prisoners' camp.
Overall, this performance is a welcome addition to the amazing classic account by Tashi which is also well worth listening for its entirely different approach, deep spirituality and especially for the synthesiser-like sonority accidentally achieved in the 6th movement where all players join in unison. So get the both recordings and see the same music can be played in totally different ways, both very inspired in its own way.
