Trying to find a book on Glazunov to get more inspiration about this composer when playing and rehearsing the quartet. I didnt find it... there's a book with ISBN# 0963545108.... The Glazunov quartet is so hard to grasp that maybe when I get to know the composer better I will have more insight in the piece. Besides that, I am making a brief analysis (harmonic) of the peice to see and hear (!) where the harmonic line takes us.
