Despite the historical prominence of the genre, I don't really listen to a lot of string quartets. It's not hard to find reasons why: I'm a wind player, so I can't exactly perform in one (nor can the people I know from sitting next to in most ensembles . . . ), most of my exploratory listening is in times and repertoires rather more recent than the core of the quartet repertoire, and the music theory courses I took tended to be centered more around art songs and piano sonatas. It will come as no surprise, then, that the ones I do know tend to be rather off the beaten path.
