>I'm gratified that the A minor Quartet made a similar impression it did on you as it did on me - which I why I included it as one of my top-three chamber piece in our "Unsung chamber music: which pieces should get heard more often?
Yes, "each single note seems to be exactly where it needs to be" is very much how I felt while listening to it. A friend, who'd admitted she didn't warm to either of the Gernsheim orchestral pieces in the opening concert, felt that the composer "completely redeemed himself" in her opinion once she heard the string quartet.
To each their own, of course (I found much to like in the orchestral works) but a point can be made that there's a compactness to Gernsheim's chamber pieces that I don't hear as much in his other works. While my mind tended to wander in the concert hall, I was (almost) on the edge of my seat while listening to the string quartet. Agreed, it's a work that absolutely deserves to be in the chamber repertoire.
